AB  - The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), responsible for the COVID-19 pandemic, has been evolving rapidly causing emergence of new variants and health uncertainties. Monitoring the evolution of the virus was of the utmost importance for public health interventions and the development of national and global mitigation strategies. Here, we report national data on the emergence of new variants, their distribution, and dynamics in a 3-year study conducted from March 2020 to the end of January 2023 in the Republic of Serbia. Nasopharyngeal and oropharyngeal swabs from 2,398 COVID-19-positive patients were collected and sequenced using three different next generation technologies: Oxford Nanopore, Ion Torrent, and DNBSeq. In the subset of 2,107 SARS-CoV-2 sequences which met the quality requirements, detection of mutations, assignment to SARS-CoV-2 lineages, and phylogenetic analysis were performed. During the 3-year period, we detected three variants of concern, namely, Alpha (5.6%), Delta (7.4%), and Omicron (70.3%) and one variant of interest—Omicron recombinant “Kraken” (XBB1.5) (<1%), whereas 16.8% of the samples belonged to other SARS-CoV-2 (sub)lineages. The detected SARS-CoV-2 (sub)lineages resulted in eight COVID-19 pandemic waves in Serbia, which correspond to the pandemic waves reported in Europe and the United States. Wave dynamics in Serbia showed the most resemblance with the profile of pandemic waves in southern Europe, consistent with the southeastern European location of Serbia. The samples were assigned to sixteen SARS-CoV-2 Nextstrain clades: 20A, 20B, 20C, 20D, 20E, 20G, 20I, 21J, 21K, 21L, 22A, 22B, 22C, 22D, 22E, and 22F and six different Omicron recombinants (XZ, XAZ, XAS, XBB, XBF, and XBK). The 10 most common mutations detected in the coding and untranslated regions of the SARS-CoV-2 genomes included four mutations affecting the spike protein (S:D614G, S:T478K, S:P681H, and S:S477N) and one mutation at each of the following positions: 5′-untranslated region (5’UTR:241); N protein (N:RG203KR); NSP3 protein (NSP3:F106F); NSP4 protein (NSP4:T492I); NSP6 protein (NSP6: S106/G107/F108 - triple deletion), and NSP12b protein (NSP12b:P314L). This national-level study is the most comprehensive in terms of sequencing and genomic surveillance of SARS-CoV-2 during the pandemic in Serbia, highlighting the importance of establishing and maintaining good national practice for monitoring SARS-CoV-2 and other viruses circulating worldwide.

AB  - Background/Objectives: Fabry disease (FD) is a rare X-linked
disorder caused by variants in the GLA gene leading to the deficiency
of lysosomal α-galactosidase-A and progressive accumulation
of globotriaosylceramide affecting the heart, nervous system,
and kidneys. FD has overlapping phenotypes and often remains
undiagnosed. Therefore, the precise molecular-genetic diagnosis
and the earliest possible treatment are essential to avoid significant
disease progression.
Methods: We analyzed 95 (34 female and 61 male) hemodialysis
patients with clinical suspicion of FD using Sanger sequencing
of all coding exons (7) and flanking intron regions of the GLA
gene, and measured the relative expression of the GLA gene in
available samples.
Results: The genetic analysis revealed 3 patients with a missense
variant (p.Asp313Tyr), and 10 patients with combinations of
non-coding variants, described as complex intronic haplotypes
(CIHs). CIH1 (c.-10C>T, c.370-81_370-77delCAGCC, c.640-16A>G,
c.1000-22C>T), the most frequent haplotype, was detected in 7
(7.4%) patients. Lyso-Gb3 biomarker levels were within the normal
range in each tested patient. However, RT-qPCR analysis revealed
decreased relative expression of GLA gene in PBMC of 2 female
patients with CIH1 and one female patient carrying only c.-10C>T
variant by 9,1%, 7,4%, 46,3%, respectively, pointing out that further
analyses are needed to confirm/exclude FD in these patients.
Conclusion: Because the effects of CIHs are not yet fully
understood, our work highlights the importance of analyzing
intronic regions of the GLA gene as genetic modifiers and the
need to include expression analysis in the diagnostic algorithm.

AB  - Background/Objectives: Primary ciliary dyskinesia (PCD) is a
disease caused by impaired ciliary motility and mainly affects the
lungs and reproductive organs. Inheritance is autosomal recessive
and X-linked with more than 40 disease-causing genes, wherefore
PCD patients have diverse clinical manifestations, thus making
diagnosis difficult. The utility of next-generation sequencing (NGS)
technology for diagnostic purposes allows a better understanding
of the PCD genetic background. However, the identification of
specific disease-causing variants is challenging. The objective of
this study was to create a unique guideline that will enable the
standardization of the assessment of novel variants within PCD
associated genes.
Methods: The study included designing a pipeline for the classification
of the rare genetic variants detected using NGS. The pipeline
included in silico (translation, 3D-model, protein-protein interactions,
sequence conservation, posttranslational modifications) and functional
analysis (expressional analysis, Western Blot) of the variants.
Results: The designed pipeline consists of three steps: sequencing,
detection, and identification of genes/variants; classification of
variants according to their effect; and variant characterization using
in silico structural and functional analysis. The pipeline was validated
by the analysis of the variants detected in a disease-causing
gene (DNAI1) and the novel candidate gene (SPAG16).
Conclusion: The application of the pipeline resulted in the
identification of disease-causing variants, as well as pathogenicity
validation, through the analysis on transcriptional, translational,
and posttranslational levels.The application of created pipeline
leads to the confirmation of PCD diagnosis and enables a shift
from candidate to disease-causing gene.

AB  - Introduction: Thalassemia syndromes are heterogeneous group of hereditary anemias characterized
by defects in the synthesis of hemoglobin (Hb) polypeptide chains. These disorders comprise thalassemias and thalassemic hemoglobin variants which are predominantly caused by mutationsin a- and
b-globin genes (HBA and HBB genes). Clinical manifestations of thalassemia syndromes range from
asymptomatic thalassemia minor to severe anemia in thalassemia major cases. The aim of thisstudy was
to update our previous findings on frequency of thalassemia mutations which result from a 13-year-old
systematic survey in Serbia.
Methods: Two hundred and fourteen patients from 149 unrelated families presented with hematological parameters indicative of thalassemia syndromes were studied. Detection of α- and β-globin gene
mutations was performed using PCR and direct sequencing.
Results: Two Hb variants and twelve different β-thalassemia mutations, including two mutations previously not reported in Serbian population, were detected. Hb variant Lepore Boston-Washington wasthe
most common cause of thalassemia, with frequency of 24.3%, followed by HBB:c.316-106C>G mutation
detected in 18.1% of families. The third most frequent cause of β-thalassemia were HBB:c.118C>T and
HBB:c.93-21G>A mutations with 16.6% incidence each. Together, these four variants account for over
75% of all mutated β-globin alleles. In addition, five families affected with α-thalassemia were detected.
Conclusion: Despite the increase in cohort size by 50% between this and our previous studies, the frequency of mutations affecting HBB gene remained unchanged. Results presented in this study will update Serbian national mutation database and contribute to better understanding of geographic history
of South European and Balkan populations.

by defects in the synthesis of hemoglobin (Hb) polypeptide chains. These disorders comprise thalassemias and thalassemic hemoglobin variants which are predominantly caused by mutationsin a- and
b-globin genes (HBA and HBB genes). Clinical manifestations of thalassemia syndromes range from
asymptomatic thalassemia minor to severe anemia in thalassemia major cases. The aim of thisstudy was
to update our previous findings on frequency of thalassemia mutations which result from a 13-year-old
systematic survey in Serbia.
Methods: Two hundred and fourteen patients from 149 unrelated families presented with hematological parameters indicative of thalassemia syndromes were studied. Detection of α- and β-globin gene
mutations was performed using PCR and direct sequencing.
Results: Two Hb variants and twelve different β-thalassemia mutations, including two mutations previously not reported in Serbian population, were detected. Hb variant Lepore Boston-Washington wasthe
most common cause of thalassemia, with frequency of 24.3%, followed by HBB:c.316-106C>G mutation
detected in 18.1% of families. The third most frequent cause of β-thalassemia were HBB:c.118C>T and
HBB:c.93-21G>A mutations with 16.6% incidence each. Together, these four variants account for over
75% of all mutated β-globin alleles. In addition, five families affected with α-thalassemia were detected.
Conclusion: Despite the increase in cohort size by 50% between this and our previous studies, the frequency of mutations affecting HBB gene remained unchanged. Results presented in this study will update Serbian national mutation database and contribute to better understanding of geographic history
of South European and Balkan populations.",

AB  - Background: The current therapy for glycogen
storage disease Ib (GSD Ib) fails to prevent the
development of renal dysfunction, and hepatocellular/
renal carcinoma in many patients. Therefore,
new therapies for the treatment of life-threatening
complications of GSD Ib are of great interest. Recent
studies revealed that chronic endoplasmic reticulum
(ER) stress and increased apoptosis are
involved in pathogenesis of GSD Ib, whereas small
molecule phenylbutyrate (4-PBA) showed the capability
of reducing ER stress-induced apoptosis.
Methods: To analyze the function of 4-PBA
as ER stress inhibitor, we created a G6PT-deficient
FlpInHEK293 cell line using the CRISPR/Cas9
knockout method and tested if 4-PBA could decrease
chronic metabolic stress and prevent cell
death. We analyzed molecular markers of unfolded
protein response (ATF4, DDIT3, HSPA5, XBP1s),
and apoptosis (BCL2/BAX, CASP3, CASP7) in
G6PT-deficient cells before and upon the treatment
using RT-qPCR method.Results: Treatment with the most effective
dose of 1 mM 4-PBA reduced the expression of
executioner caspases (CASP3, CASP7) and increased
the BCL2/BAX ratio, indicating a reduced
apoptosis level. Additionally, 4-PBA decreased
UPR marker expression in G6PT-deficient cells.
Our results proved the concept that 4-PBA could
alleviate markers of ER stress detected in the GSD
Ib in vitro model system and prevent cell death.
Conclusion: We demonstrated, for the first
time, the potential of 4-PBA to be repurposed for
patients with GSD Ib and open perspectives for
translational research that could contribute to a
knowledge of GSD Ib treatments and other genetic
diseases where chronic ER stress-induced apoptosis
contribute to the disease pathology.

AB  - Background: Childhood epilepsies are
caused by heterogeneous underlying disorders where
approximately 40% can be attributed to genetic
factors. Application of next-generation sequencing
(NGS) has revolutionized diagnostics and therefore
has enabled the identification of disease-causing
genes and variants in childhood epilepsies.
Materials and Methods: Patients who presented
with epilepsy of unknown etiology in childhood,
with suspicion of a genetic cause were included
in this study. In total, 55 patients from unrelated
non-consanguineous families were included and analyzed
by NGS either using clinical-exome sequencing
(MiSeq, Illumina) or whole-exome sequencing
(DNBSEQ-G400, MGI). Variants were prioritized
using Variant Interpreter and VarSome and classified
according to the ACMG recommendations.
Results: Using CES we analyzed 38 patients,
and for 22 of them a diagnosis was established.
Using WES we analyzed 17 patients with childhood epilepsy, which led to the identification of
disease-causing genes in 11 patients. The diagnostic
success rate for CES was 55.3% (21/38) and the
diagnostic rate for WES was 64.7% (11/17), with
the overall diagnostic rate being 58.2% (32/55). For
these patients, we detected pathogenic, likely pathogenic
variants or VUS in 24 epilepsy genes that
correlate well to the observed phenotype. Sixteen
novel genetic variants were identified and characterized
using various in silico algorithms.
Conclusion: This is the first study reporting
the molecular-genetic basis of childhood epilepsy
in Serbia. The prompt establishment of a specific
diagnosis is essential in order to make available the
prognosis, optimize therapy, and enable counseling
on recurrence risk in future pregnancies.

AB  - Primary ciliary dyskinesia (PCD) is a rare motor ciliopathy, which predominantly affects the lungs and
reproductive organs. PCD has a heterogeneous genetic basis, and it is necessary to analyze more than
40 causative genes in order to establish a precise diagnosis, which is essential for optimal treatment and
adequate genetic counseling. Five patients suspected of PCD were analyzed using next-generation
sequencing (NGS). The pathogenicity of the genetic variants was tested by in silico, qRT-PCR and
Western blot methods. Two newly discovered variants p.N450Lfs*6 and p.D562N in the DNAI1 gene
were detected in one patient suspected of PCD. The results of in silico prediction showed that the
p.N450Lfs*6 variant affects the structure of the 3D model of the protein, abolishes ligand binding sites
and post-translational modifications, thereby disrupting protein-protein interactions (PPI). The
p.D562N variant has no effect on the 3D structure of the protein, but affects the ligand binding site and
is located in the WD-40 domain, which most likely disrupts PPI. The results of the qRT-PCR method
showed a decreased expression level of DNAI1 mRNA by about 50% in the patient compared to the
control group, while Western blot analysis showed the presence of two protein products (699 ak and
455 ak). By analyzing the obtained results, it was concluded that the changes p.N450Lfs*6 and
p.D562N affect the length and quantity of the DNAI1 protein, leading to the loss of protein function
and are responsible for the occurrence of primary ciliary dyskinesia in the analyzed patient.

AB  - COVID-19 pandemic has proved to be an unrelenting health threat for more than a year now. The
emerging amount of data indicates that vitamin D could be important for clinical presentation of
COVID-19. Here, we investigated association of genetic variants related to the altered level and
bioavailability of vitamin D with clinical severity of COVID-19. We analyzed variants in genes
significant for the status of vitamin D (DHCR7/NADSYN1 rs12785878, GC rs2282679, and CYP2R1
rs10741657), and vitamin D effect (VDR rs2228570) in 120 Serbian adult and pediatric COVID-19
patients using allelic discrimination. Furthermore, we carried out comparative population genetic
analysis among European and other worldwide populations to investigate variation in allelic
frequencies of selected variants. The results showed that DHCR7/NADSYN rs12785878 and CYP2R1
rs10741657 variants were associated with severe COVID-19 in adults (p = 0.03, p = 0.017,
respectively); carriers of DHCR7/NADSYN TG+GG and CYP2R1 GG genotypes had 0.21 and 5.9 the
odds for developing severe disease, OR 0.21 (0.05–0.9) and OR 5.9 (1.4–25.2), respectively. There
were no associations between selected genetic variants and disease severity in pediatric patients.
Comparative population genetic analysis revealed that Serbian population had the lowest frequency of
CYP2R1 rs10741657 G allele compared to other non-Finish Europeans (0.58 compared to 0.69 and
0.66 in Spanish and Italian population, respectively), suggesting that other populations should also
investigate the relationship of CYP2R1 variant and the COVID-19 disease course. The results of the
study indicated that vitamin D related genetic variants were implicated in severe COVID-19 in adults.
This could direct prevention strategies based on population specific nutrigenetic profiles.

AB  - Introduction: Glycogen storage disease type Ib (GSD-Ib) is an autosomal recessive disorder characterized by fasting hypoglycemia and the accumulation of glycogen in the liver, kidneys and intestinal mucosa. Recent studies revealed that chronic endoplasmic reticulum (ER) stress and increased apoptosis
play a role in the progression of disease manifestations. Although dietary control is commonly utilized
to manage hypoglycemia, there is still a lack of effective pharmacological therapy. Therefore, the establishment of proper model system is essential for testing novel treatment approaches.
Methods: To create GSD-Ib in vitro model system, CRISPR/Cas9-knockout (KO) method was used to introduce a deletion in SLC37A4 gene in the FlpInHEK293 cells. Characterization of CRISPR/Cas9-KO model
system was performed using Sanger sequencing, RT-qPCR and Western Blot. Additionally, the expression analysis of ER stress and apoptotic markers was performed.
Results: Sanger sequencing confirmed the presence of c.14_100del in SLC37A4 gene. The expression
level of SLC37A4 was decreased to 26.8% in the SLC37A4-/- cell line compared to the SLC37A4 wild-type
along with Western blot analysis, which confirmed reduced target protein level in SLC37A4-/- clones. Furthermore, ER stress (ATF4, DDIT3, HSPA5, XBP1s) and apoptotic (BCL2, BAX, CASP3, CASP7) markers expression levels were significantly altered in SLC37A4-/- clones compared to wild-type, which proved that
we created a suitable GSD-Ib in vitro model system.
Conclusion: Utilizing CRISPR/Cas9 technology, we established cellular GSD-Ib modelsystem that mirrors
increased ER stress and apoptosis. This model system could be used to facilitate a comprehensive understanding of disease mechanisms and enable testing of potential treatment effectiveness.

AB  - Introduction: All inborn metabolic diseases are rare, having a prevalence less than 1:2000. Vast majority of them are monogenic and finding pathogenic genetic variantsis needed to setthe correct diagnosis, enable adequate treatment and provide genetic counseling to members of affected family. Thisstudy is an overview of genomic studies of rare metabolic diseases in Serbia. Methods: Since 2005, more than 300 patients suspected to have a rare metabolic or neurometabolic disease have been analyzed using sanger sequencing, clinical-exome sequencing, whole-exome sequencing or whole-genome sequencing in order to find disease-causing or disease-modifying variants. Novel variants were characterized using in silico modelling or in in vitro eukaryotic assays (standard or CRISPR/Cas9 developed). Results: Disease-causing variants were found in more than 60 different genes associated with a metabolic or neurometabolic disease. The most frequent disease was phenylketonuria (109 patients), followed by glycogen storage disease Ib (30 patients), while majority of diseases is seen only in a single patient. More than 40 new genetic variants were comprehensively characterized in silico or in vitro. For the first time, candidate modifiers (SHANK gene family) were identified in a group of phenylketonuria patients with an unusual phenotype. Conclusion: In the genomics era, next-generation sequencing significantly shortens time to diagnosis and allowsstudying genetic modifiers of monogenic diseases and genotype-phenotype correlation. Furthermore, characterization of novel genetic targets boosts development of precision medicine

AB  - Fabry disease (FD) is a rare X-linked disorder caused by variants in the GLA gene leading to the
deficiency of lysosomal α-galactosidase-A and progressive accumulation of globotriaosylceramide
affecting the heart, nervous system, and kidneys. FD has overlapping phenotypes and often remains
undiagnosed. Therefore, a precise molecular-genetic diagnosis and the earliest possible treatment are
essential to avoid significant disease progression. The study aimed to determine the strategy for
establishing routine molecular genetic diagnostics of FD in Serbia to provide an early application of
appropriate therapy and genetic advice to families with a high risk for the birth of a child with FD. We
analyzed 95 (34 female and 61 male) hemodialysis patients with clinical suspicion of FD using Sanger
sequencing of all coding exons (7) and flanking intron regions of the GLA gene and measured the
relative expression of the GLA gene in available samples. The genetic analysis revealed 3 patients with
a missense variant (p.Asp313Tyr), and 10 patients with combinations of non-coding variants, described
as complex intronic haplotypes (CIHs). CIH1 (c.-10C>T, c.370-81_370-77delCAGCC, c.640-16A>G,
c.1000-22C>T), the most frequent haplotype, was detected in 7 (7.4%) patients. Lyso-Gb3 biomarker
levels were within the normal range in each tested patient. However, RT-qPCR analysis revealed
decreased relative expression of the GLA gene in PBMC of 2 female patients with CIH1 and one
female patient carrying only c.-10C>T variant by 9,1%, 7,4%, 46,3%, respectively, pointing out that
further analyses are needed to confirm/exclude FD in these patients. Because the effects of CIHs are not
yet fully understood, our work highlights the importance of analyzing intronic regions of the GLA gene
as genetic modifiers and the need to include expression analysis in the diagnostic algorithm.

AB  - Introduction: Phenylketonuria (PKU) is the most frequent inborn disorder of amino acid metabolism
caused by variants in human phenylalanine hydroxylase gene (PAH).
Methods: In thisstudy (an update for the time period of 10 years, with patientsfrom our previousstudies included) a total of 109 PKU patients from Serbia were analyzed. They were classified into three phenotypic categories in accordance with pre-treatment plasma phenylalanine level: classic PKU, mild PKU
and mild hyperphenylalaninemia. For genetic analyses, we combined Sanger sequencing, MLPA and
next generation sequencing to identify disease-causing variantsin PAH gene, which were further classified using ACMG classification. Additionally, we used in silico and/or eukaryotic expression studiesto assess the effect of novel genetic variants identified in our patients.
Results: Disease-causing variants were identified in 217 of 218 alleles, reaching detection rate of 99.5%.
We detected a total of 32 different variants, of which 29 previously described and three novel ones:
p.Gln226Lys, p.Pro244His and p.Pro416Leu. In silico and/or eukaryotic expression studies confirmed pathogenic effect of all novel genetic variants. The most frequent variant was p.Leu48Ser (31.2%), followed
by p.Arg408Trp (13.8%), p.Ile306Val (9.2%). p.Glu390Gly (5%), p.Pro281Leu (4.6%), and p.Arg261Gln
(3.2%). All detected disease-causing variants were classified as pathogenic using ACMG classification.
Conclusion: Our study brings the updated spectrum of molecular genetic data, variant classification
and detailed phenotypic characteristicsfor PKU patientsfrom Serbia. Therefore, ourstudy contributesto
better understanding of molecular landscape of PKU in Europe and to general knowledge on genotype–
phenotype correlation in PKU.

AB  - Rare lung diseases (RLDs) are a group of diseases that individually affect one in 2,000 people, with an
estimate that about 80% of RLDs have a genetic origin. Despite the variations among RLDs in clinical
characteristics and manifestations, most of these diseases similarly damage the lungs, making diagnosis
difficult. The utility of NGS technology in RLDs for diagnostic purposes allows a better understanding
of the genetic background, however, the identification and classification of disease-causing variants are
challenging. Further, numerous VUS (variants of uncertain significance) that cannot be precisely
defined and classified are produced. The main goal of this study was to create a unique guideline that
will enable the standardization of the assessment of novel genetic variants in RLDs causative genes.
The designed pipeline consists of three main steps: (1) sequencing, detection, and identification of
genes/variants, (2) classification of variants, and (3) characterization of variants using in silico
structural and functional analysis. The pipeline validation was performed through the analysis of
variants detected in a disease-causing and candidate genes of one of the RLDSs, and detected VUS
variants have gained diagnostic significance. The application of this pipeline resulted in the
identification and classification of novel variants, through analysis at the transcriptional, translational,
and posttranslational levels, and led to accurate diagnosis.

genes/variants, (2) classification of variants, and (3) characterization of variants using in silico
structural and functional analysis. The pipeline validation was performed through the analysis of
variants detected in a disease-causing and candidate genes of one of the RLDSs, and detected VUS
variants have gained diagnostic significance. The application of this pipeline resulted in the
identification and classification of novel variants, through analysis at the transcriptional, translational,
and posttranslational levels, and led to accurate diagnosis.",

AB  - Introduction: Primary ciliary dyskinesia is a rare and heterogeneous disorder primarily affecting the respiratory organs, with impaired mucociliary clearance being a common characteristic. Recently, the importance of the miR34/449 family in ciliogenesisin animal models has been described. Thisstudy aimed
to establish a modelsystem to study respiratory diseases and assessfor the first time the role of the miR34 family on the mucociliary process in humans.
Methods: We cultured the primary Normal Human Bronchial Epithelial (NHBE) cells in the air-liquid interface system, enabling the differentiation of multiciliated cells(MCCs) and goblet cells(GCs). During the
differentiation process, transient overexpression of miR-34a/b/c members was conducted. The model
system and treatments were validated through confocal microscopy (β-tubulin, MUC5B, MUC5AC antibodies) and qRT-PCR of miRNAs,specifically ciliogenesis markers(NOTCH1, MCIDAS, GEMC1, CCNO, RFX3),
and differentiated cell markers (FOXJ1 and TFF3).
Results: Expression levels of ciliogenesis and differentiated cells markers and detection of cilia and
mucins at confocal microscopy confirmed the successful establishment of cellular modelsystem. During
the initial differentiation stage, an overexpression of miR34a/b/c changed the expression profile of ciliogenesis and differentiated cell markers.
Conclusion: The established model system provides a valuable platform for exploring innovative treatment approaches for lung diseases. These findings suggest that overexpression of miR34a/b/c has impact on mucociliary process by reducing the duration required for the process of ciliogenesis.
Furthermore, the expression levels of differentiated cell markerssuggest increased number of MCCs and
decreased number of GCs, indicating the role of miR34a/b/c in enhancing mucociliary clearance.

AB  - Introduction: Rare diseases are heterogeneous group of diseases, with one common characteristics, a
prevalence less than 1 in 2000 people. Vast majority of them are monogenic and finding pathogenic genetic
variants is needed to set the correct diagnosis, enable adequate treatment and provide genetic counselling to
members of affected family. This study is an overview of genomic studies of rare diseases in Serbia.
Methods: More than 1200 patients suspected to have a rare disease have been analyzed using sanger
sequencing, clinical-exome sequencing, whole-exome sequencing or whole-genome sequencing in order to
find disease-causing or disease-modifying variants. Novel variants were characterized using in silico modelling
or in in vitro eukaryotic assays (standard or CRISPR/Cas9 developed).
Results: Disease-causing variants were found in more than 150 different genes associated with a rare
disease. The most frequent were thalassemia syndromes (214 patients), followed by phenylketonuria (109
patients), congenital adrenal hyperplasia (>90 patients) and glycogen storage disease Ib (30 patients), while
majority of diseases is seen only in a single patient. More than 40 new genetic variants were comprehensively
characterized in silico or in vitro. For the first time, candidate modifiers (SHANK gene family) were identified
in a group of phenylketonuria patients with an unusual phenotype.
Conclusion: In the genomics era, next-generation sequencing significantly shortens time to diagnosis
and allows studying genetic modifiers of monogenic diseases and genotype-phenotype correlation. Furthermore,
characterization of novel genetic targets boosts development of precision medicine.

AB  - Introduction: Glycogen storage disease type Ib (GSD-Ib) is characterized by a deficiency of glucose-6-
phosphate translocase (G6PT) encoded by the SLC37A4 gene, affecting glucose homeostasis and disrupting autophagy. Recent findings suggest that G6PT may also play a role in autophagy and
glycogen-selective autophagy (glycophagy) activation independent of its transport function. To investigate this hypothesis, two groups of GSD-Ib patients carrying variants with different effects on G6PT
transport activity and stability (p.Asn27Lys and p.Leu348Valfs*53), were compared to the control group
of subjects.
Methods: The relative expression levels of SLC37A4 gene, autophagy (mTOR, ULK1, PRKAG1), and glycophagy markers(GABARAPL1, GAA, STBD1) were assessed in mononuclear cells of GSD Ib patients(four
carrying p.Asn27Lys and four carrying p.Leu348Valfs*53 variant) compared to control group using RTqPCR. Statistical analysis was performed using one-way ANOVA followed by a post-hoc t-test.
Results: The p.Asn27Lys group exhibited 1.5-2.5 times higher expression of SLC37A4 and autophagy
markers, while the p.Leu348Valfs*53 group showed downregulation by approximately 50% compared to
the control group. Glycophagy markers were increased twofold in both patient groups, except for GAA,
which had similar expression levels as the control group.
Conclusion: Individuals carrying the p.Asn27Lys variant display the presence of SLC37A4 transcript in
their cells, which correlates with autophagy activation. Conversely, in patients with the p.Leu348Valfs*53
variant SLC37A4 is downregulated, indicating compromised autophagy activation. These findings support the role of G6PT in autophagy activation, independent of itstransport activity. Furthermore, the elevated expression of glycophagy markers observed in both patient groups can be attributed to the
accumulated glycogen.

2.000 људи, са проценом да око 80% РПБ има генетичку основу. Упркос
варијацијама међу РПБ у клиничким карактеристикама и манифестацијама, већина
ових болести на сличан начин оштећује плућа, што отежава успостављање
дијагнозе. Употреба НГС технологије (енгл. Next Generation Sequencing, NGS) у
дијагностичке сврхе омогућава боље разумевање генетичке основе болести,
међутим, идентификација и класификација варијанти које изазивају болести је
комплексна због детекције бројних ВУС варијанти (енгл. Variants of uncertain
significance, VUS) које се не могу прецизно класификовати. Главни циљ ове студије
био је да се дизајнира јединствени водич који ће омогућити стандардизацију
анализе нових генетичких варијанти у генима узрочницима РПБ. Дизајниране
смернице се састоје од три главна корака: (1) секвенцирање, детекција и
идентификација гена/варијанти, (2) класификација варијанти и (3) карактеризација
варијанти коришћењем in silico структурне и функционалне анализе (qRT-PCR и
Western blot анализа). Валидација смерница је извршена анализом варијанти
откривених у гену узрочнику и гену кандидату за РПБ, а детектоване ВУС
варијанте су добиле дијагностички значај. Примена ових смерница је резултирала
идентификацијом и класификацијом новооткривених генетичких варијанти, кроз
анализу на транскрипционом, транслационом и посттранслационом нивоу, и
довела до успостављања прецизне дијагнозе болести.",

AB  - Fabrijeva bolest (FB) je retka, monogenska bolest, koja se odlikuje veoma
heterogenom kliničkom slikom izazvanom promenama u genu GLA, smeštenom na
dugom kraku hromozoma H. Usled narušene funkcije lizozomalnog enzima α-
galaktozidaze A dolazi do nagomilavanja Gb3 supstrata, što dovodi do
multisistemskih oštećenja. Precizna molekularno-genetička dijagnoza je
esencijalna kako bi se pacijentima omogućilo pravovremeno lečenje. U našoj
studiji, analizirano je 95 ispitanika suspektnih na FB Sangerovim
sekvenciranjem svih egzona i okolnih intronskih regiona gena GLA, nakon čega je
izmerena relativna ekspresija kod 6 pacijenata. Genetičkom analizom kod 3
pacijenta detektovana je kodirajuća varijanta (p.D313Y), dok je kod 10 pacijenata
detektovana kombinacija intronskih varijanti, opisanih kao kompleksni
intronski haplotip (KIH). KIH1 (c.-10C>T, c.370-81_370-77delCAGCC, c.640-
16A>G, c.1000-22C>T), najčešći haplotip, detektovan je kod 7 (7,4%) pacijenata.
Uprkos normalnim biohemijskim parametrima, rezultati RT-qPCR metode
pokazali su snižen nivo ekspresije gena GLA u perifernoj krvi za 9,1%, 7,4%,
46,3% kod dve pacijentkinje (KIH1) i jedne pacijentkinje kod koje je detektovana
promotorska varijanta c.-10C>T, respektivno, ukazujući na potrebu dodatnih

AB  - Glycogen storage diseases (GSDs) are rare metabolic monogenic disorders characterized by an excessive accumulation of glycogen in the cell. However, monogenic disorders are not simple regarding genotype-phenotype correlation. Genes outside the major disease-causing locus could have modulatory effect on GSDs, and thus explain the genotype-phenotype inconsistencies observed in these patients. Nowadays, when the sequencing of all clinically relevant genes, whole human exomes, and even whole human genomes is fast, easily available and affordable, we have a scientific obligation to holistically analyze data and draw smarter connections between genotype and phenotype. Recently, the importance of glycogen-selective autophagy for the pathophysiology of disorders of glycogen metabolism have been described. Therefore, in this manuscript, we review the potential role of genes involved in glycogen-selective autophagy as modifiers of GSDs. Given the small number of genes associated with glycogen-selective autophagy, we also include genes, transcription factors, and non-coding RNAs involved in autophagy. A cross-link with apoptosis is addressed. All these genes could be analyzed in GSD patients with unusual discrepancies between genotype and phenotype in order to discover genetic variants potentially modifying their phenotype. The discovery of modifier genes related to glycogen-selective autophagy and autophagy will start a new chapter in understanding of GSDs and enable the usage of autophagy-inducing drugs for the treatment of this group of rare-disease patients.

AB  - Introduction/Objective Fabry disease (FD) is an X-linked lysosomal storage disease that develops as a consequence of mutation in the Alpha-galactosidase A (GLA) gene. There are more than 1080 known variants in the GLA gene. Some of them are pathogenic, but most of them are benign or represent the genetic change that can be classified as a genetic variant of unknown significance or simply be a representation of genetic polymorphism. There are two main features of FD, classic form and late-onset variants of disease. The main target organs in patients with FD are the kidneys, heart, and nervous system. Bearing in mind the fact that FD is a rare disease, the best way for active searching of patients is high-risk population screening, after which family screening for every proband case should be performed. Methods In this paper, we present results of a multicentric pilot study that represents findings from the screening of hemodialysis patients for FD in six hemodialysis units in Vojvodina. Results We have found one patient with benign mutation and 16 patients with genetic polymorphisms in GLA gene. We have learned that genetic changes in GLA gene can be frequent, but very rarely are of clinical significance and lead to manifestations of FD.

AB  - Background: COVID-19 pandemic has proved to be an unrelenting health threat for more than a year now. The emerging amount of data indicates that vitamin D, zinc and selenium could be important for clinical presentation of COVID-19. Here, we investigated association of genetic variants related to the altered level and bioavailability of vitamin D, zinc and selenium with clinical severity of COVID-19. Methods: We analyzed variants in genes significant for the status of vitamin D (DHCR7/NADSYN1 rs12785878, GC rs2282679, CYP2R1 rs10741657, and VDR rs2228570), zinc (PPCDC rs2120019) and selenium (DMGDH rs17823744) in 120 Serbian adult and pediatric COVID-19 patients using allelic discrimination. Furthermore, we carried out comparative population genetic analysis among European and other worldwide populations to investigate variation in allelic frequencies of selected variants. Results: Study showed that DHCR7/NADSYN rs12785878 and CYP2R1 rs10741657 variants were associated with severe COVID-19 in adults (p = 0.03, p = 0.017, respectively); carriers of DHCR7/NADSYN TG+GG and CYP2R1 GG genotypes had 0.21 and 5.9 the odds for developing severe disease, OR 0.21 (0.05-0.9) and OR 5.9 (1.4-25.2), respectively. There were no associations between selected genetic variants and disease severity in pediatric patients. Comparative population genetic analysis revealed that Serbian population had the lowest frequency of CYP2R1 rs10741657 G allele compared to other non-Finish Europeans (0.58 compared to 0.69 and 0.66 in Spanish and Italian population, respectively), suggesting that other populations should also investigate the relationship of CYP2R1 variant and the COVID-19 disease course. Conclusion: The results of the study indicated that vitamin D related genetic variants were implicated in severe COVID-19 in adults. This could direct prevention strategies based on population specific nutrigenetic profiles.

AB  - Clustered Regularly Interspaced Short Palindromic Repeats/CRISPR associated protein 9 (CRISPR/Cas9) is a
naturally occurring genome editing tool adopted from the prokaryotic adaptive immune defense system.
Due to its high efficiency and precision, the Cas9 protein derived from the type II CRISPR system, has found
applications in many fields of science. Currently, CRISPR/Cas9-based genome editing has become one of
the most promising tools for treating human genetic diseases, including cardiovascular diseases, neurodegenerative
disorders, and various types of tumors. CRISPR/Cas9-based gene therapy is extensively studied
in preclinic and clinic treatments. CRISPR/Cas9 genome editing is also a robust tool to create in vitro cellular
and animal model systems for investigating and treating human genetic disorders, particularly diseases
associated with point mutations. Therefore, in this review, we will present a brief history and mechanism of
the CRISPR/Cas9 system. We will also describe the different methodological approaches, review applications
in biomedicine and describe its role in the development of new molecular therapeutics for rare inherited
diseases.

AB  - Primary ciliary dyskinesia (PCD) is a disease caused by impaired function of motile cilia. PCD mainly affects the lungs and reproductive organs. Inheritance is autosomal recessive and X-linked. PCD patients have diverse clinical manifestations, thus making the establishment of proper diagnosis challenging. The utility of next-generation sequencing (NGS) technology for diagnostic purposes allows for better understanding of the PCD genetic background. However, identification of specific disease-causing variants is difficult. The main aim of this study was to create a unique guideline that will enable the standardization of the assessment of novel genetic variants within PCD-associated genes. The designed pipeline consists of three main steps: (1) sequencing, detection, and identification of genes/variants; (2) classification of variants according to their effect; and (3) variant characterization using in silico structural and functional analysis. The pipeline was validated through the analysis of the variants detected in a well-known PCD disease-causing gene (DNAI1) and the novel candidate gene (SPAG16). The application of this pipeline resulted in identification of potential disease-causing variants, as well as validation of the variants pathogenicity, through their analysis on transcriptional, translational, and posttranslational levels. The application of this pipeline leads to the confirmation of PCD diagnosis and enables a shift from candidate to PCD disease-causing gene.
