Abstract
BRAT1 biallelic variants are associated with rigidity and multifocal seizure syndrome, lethal neonatal (RMFSL), and neurodevelopmental disorder associating cerebellar atrophy with or without seizures syndrome (NEDCAS). To date, forty individuals have been reported in the literature. We collected clinical and molecular data from 57 additional cases allowing us to study a large cohort of 97 individuals and draw phenotype-genotype correlations. Fifty-nine individuals presented with BRAT1-related RMFSL phenotype. Most of them had no psychomotor acquisition (100%), epilepsy (100%), microcephaly (91%), limb rigidity (93%), and died prematurely (93%). Thirty-eight individuals presented a non-lethal phenotype of BRAT1-related NEDCAS phenotype. Seventy-six percent of the patients in this group were able to walk and 68% were able to say at least a few words. Most of them had cerebellar ataxia (82%), axial hypotonia (79%) and cerebellar atrophy (100%). Genotype-phenotype correlations in our cohort revealed that biallelic nonsense, frameshift or inframe deletion/insertion variants result in the severe BRAT1-related RMFSL phenotype (46/46; 100%). In contrast, genotypes with at least one missense were more likely associated with NEDCAS (28/34; 82%). The phenotype of patients carrying splice variants was variable: 41% presented with RMFSL (7/17) and 59% with NEDCAS (10/17).

Abstract
BACKGROUND Despite the fact that numerous studies have investigated the association between genetic polymorphisms and colorectal cancer (CRC), more research is required to comprehend the molecular mechanisms of CRC. In the present study, we investigated the association between lncRNA HOTAIR rs2366152 and rs1899663 polymorphisms with CRC susceptibility in the Iranian population. METHODS This case-control study consisting of 187 CRC patients and 200 healthy samples. The tetra-amplification refractory mutation system-polymerase chain reaction (Tetra-ARMS-PCR) technique was used for the genotyping of rs2366152 and rs1899663 polymorphisms. RESULTS The findings showed that the AG genotype of the rs2366152 polymorphism has a protective effect on CRC susceptibility (OR = 0.60, 95% CI: 0.38-0.94, p-value = 0.023). Furthermore, rs2366152 polymorphism associated with CRC risk in an over dominant inheritance model (p-value = 0.0089). According to the outcomes of the rs1899663 polymorphism, the GT genotype had protective effects on CRC risk (OR = 0.55, 95% CI: 0.35-0.86, p-value = 0.008). Moreover, statistical analysis has shown that the rs1899663 polymorphism was associated with CRC risk in dominant (p-value = 0.013) and overdominant (p-value = 0.0086) inheritance models in the Iranian population. CONCLUSION This study confirmed that HOTAIR rs2366152 and rs1899663 polymorphisms associated with CRC risk in different inheritance models. It is indeed necessary to do additional research to verify our findings.

Abstract
Background Gnathodiaphyseal dysplasia (GDD) is an ultrarare autosomal dominant bone dysplasia characterized by cementoosseous lesions of the jawbones, bone fragility, frequent bone fractures at the young age, bowing of tubular bones, and diaphyseal sclerosis of long bones associated with generalized osteopenia. GDD is caused by point mutations in anoctamin‐5 (ANO5) on chromosome 11p14.3. For the past few years, next generation sequencing (NGS) technology has facilitated the discovery of causative variants in genetically heterogeneous diseases. Methods In this study, exome sequencing (ES) was performed using the DNA sample of the proband. Family histories and clinical information were collected through comprehensive medical examination and genetic counseling. Results ES results identified a heterozygous variant, NM_213599.3:c.1078T>C(p.Cys360Arg) in the ANO5 gene. Sanger sequencing was performed to confirm the detected pathogenic variant in DNA samples of the entire family (except deceased individuals), which segregated with the disease within the family. Finally, in silico analysis was applied to test the pathogenicity of the variant using various online software. Conclusion In summary, our investigation identified a novel pathogenic variant in the ANO5, responsible for gnathodiaphyseal dysplasia in a large Iranian family. Therefore, based on the present study, this variant can be helpful for diagnosis and effective management of GDD patients. Gnathodiaphyseal dysplasia (GDD) is an ultrarare autosomal dominant bone dysplasia characterized by cementoosseous lesions of the jawbones, bone fragility, frequent bone fractures at the young age. In this study, Exome Sequencing results identified a heterozygous mutation, NM_213599.3:c.1078T>C(p.Cys360Arg) in the ANO5 confirmed by Sanger sequencing.

Abstract
Background Despite many efforts to discover the important role of the autophagy process in the pathogenesis of colorectal cancer (CRC), the exact involved molecular mechanism still remains to be elucidated. Recently, a limited number of studies have been employed to discover the impact of autophagy genes’ variants on the development and progression of CRC. Here, we evaluated the association between two single‐nucleotide polymorphisms (SNPs) in the main components of the autophagy genes, ATG16L1 rs2241880, and ATG5 rs1475270, and the CRC risk in an Iranian population. Methods During this investigation, a total of 369 subjects, including 179 CRC patients and 190 non‐cancer controls have been genotyped using Tetra‐primer amplification refractory mutation system‐polymerase chain reaction (TP‐ARMS‐PCR) method. Result The results demonstrated that the T allele of the ATG16L1 rs2241880 was significantly associated with the increased risk of CRC in the studied population (OR 1.64, 95% CI: 1.21–2.22, p = 0.0015). Moreover, ATG16L1 rs2241880 TT genotype increased the susceptibility to CRC (OR 3.31, 95% CI: 1.64–6.69, p = 0.0008). Furthermore, a significant association was observed under the recessive and dominant inheritance models (p = 0.0015 and p = 0.017, respectively). No statistically significant differences were found in the ATG5 rs1475270 alleles and genotypes between the cases and controls. Conclusion The results of the present study may be helpful concerning the risk stratification in CRC patients based on the genotyping approach of autophagy pathways and emphasize the need for further investigations among different populations and ethnicities to refine our conclusions.

Abstract
HECT And RLD Domain-Containing E3 Ubiquitin Protein Ligase 2, or HERC2, codes an ubiquitin ligase that has an important role in key cellular processes including cell cycle regulation, DNA repair, mitochondrial functions, and spindle formation during mitosis. While HERC2 Neurodevelopmental Disorder in Old Order Amish is a well characterized human disorder involving HERC2, bi-allelic HERC2 loss of function has only been described in three families and results in a more severe neurodevelopmental disorder. Herein, we delineate the HERC2 loss of function phenotype by describing three previously unreported patients, and by summarizing the molecular and phenotypic information of all known HERC2 missense variants and biallelic loss of function patients. Collectively, these twelve individuals present with recurring features that define a syndrome with varying combinations of severe neurodevelopmental delay, structural brain anomalies, seizures, hypotonia, feeding difficulties, hearing and vision issues, and renal anomalies. This study describes a distinct neurodevelopmental disorder, emphasizing the importance of further characterization of HERC2-related disorders, as well as highlighting the importance of ongoing work into understanding these critical neurodevelopmental pathways.

Abstract
BACKGROUND The myosin 1H (MYO1H) gene, located on chromosome 12, encodes the unconventional MYO1H protein, which is involved in the intracellular movement and morphology of chondrocytes, and plays a vital role in the prognathism or retrognathism of the mandible. OBJECTIVES The objective of this study was to assess the relationship between the polymorphisms of the MYO1H gene and mandibular prognathism in the Iranian population. MATERIAL AND METHODS The current project evaluated 64 patients with mandibular prognathism requiring orthognathic surgery and 60 controls with skeletal class I occlusion. Genome amplification was performed using specific primer pairs to assess the rs10850110 and rs11611277 polymorphisms of the MYO1H gene through the polymerase chain reaction (PCR). The restriction fragment length polymorphism (RFLP) technique was used to detect single-nucleotide polymorphisms. The data was analyzed using the χ2 test. RESULTS The patient and control groups were not significantly different in terms of age or gender (p > 0.05). In all, 3.1% of patients and 6.7% of controls had the rs10850110 polymorphism (p = 0.680), and 1.6% of patients and 5% of controls had the rs11611277 polymorphism (p = 0.602). CONCLUSIONS No significant correlation was noted between the rs10850110 and rs11611277 polymorphisms of the MYO1H gene and mandibular prognathism in the Iranian population. However, the lower frequency of these polymorphisms in the patient group suggests a possible association with mandibular retrognathism, which needs to be investigated with a larger sample size.

Abstract
Glycogen storage diseases (GSDs) are the heterogeneous group of disorders caused by mutations in at least 30 different genes. Different types of GSDs, especially liver GSDs, take overlapping symptoms and can be clinically indistinguishable. This survey evaluated the use of whole-exome sequencing (WES) for the genetic analysis of the liver GSD-suspected patients in three unrelated families. An in-house filtering pipeline was used to assess rare pathogenic variants in GSD-associated genes, autosomal recessive/mendelian disorder genes (carrier status for genetic counseling subjects), and the ACMG's list of 59 actionable genes. For the interpretation of the causative variants and the incidental/secondary findings, ACMG guidelines were applied. Additionally, we have explored PharmGKB class IA/IB pharmacogenetic variants. The segregation analysis was performed using Sanger sequencing for the novel causative variants. Bioinformatics analysis of the exome data in three individuals revealed three novel homozygous causative variants in the GSD-associated genes. The first variant, c.298_307delATGATCAACC in PYGL gene has related to HERS disease (GSD VI). Both variants of c.1043dupT and c.613-1G > C in SLC2A2 gene have been associated with Fanconi-Bickel syndrome (GSDXI). Eight pathogenic/likely pathogenic medical actionable findings in Mendelian disease genes and 10 pharmacogenetic variants with underlying drug response phenotypes have been identified. No known/expected pathogenic variants were detected in the ACMG's list of 59 actionable genes. The logical filtering steps can help in finding other medical actionable secondary/incidental findings as well as effectively identifying the causative variants in heterogeneous conditions such as GSDs. Three novel variants related to GSD genes recognized in liver GSD-suspected patients with early infantile and childhood-age onset.

Abstract
Disorders of sex development (DSD) are different types of conditions that their accurate diagnosis by using conventional phenotypic and biochemical approaches is a challenging issue. Precise determination of DSD is critical due to the detection of possible life-threatening associated disorders. It may also assist parents in choosing the most suitable management for their affected child. In this study, two affected kids born from consanguineous families who were clinically diagnosed for sex development disorder were investigated for the main cause of the disease. Biochemical analysis failed to make an accurate diagnosis. Karyotype analysis showed an abnormal sex chromosome pattern. Whole exome sequencing was sequentially applied to precisely ascertain the genetic cause of the disease. A novel deletion, g.40936_53878del12943insTG (NG_008365.1), and one known mutation, c.586G>A (p.Gly196Ser), were detected in SRD5A2 gene in case I and case II respectively. Further analysis was performed using polymerase chain reaction, primer walking and Sanger sequencing to detect the nucleotides changes accurately. Segregation analysis in the families confirmed 13kb novel homozygous deletion of SRD5A2 in case I and c.586G>A in case II. The present study confirms the diagnostic value of whole exome sequencing in the detection of DSD aetiology, especially when several differential diagnoses are possible.

Abstract
Aim: rs2585428 and rs4809960 polymorphisms were significantly associated with overall cancer risk, but there is no evidence regarding the overall colorectal cancer (CRC) risk. Materials & methods: A total of 505 subjects, including 246 patients with CRC and 259 noncancer controls participated in the study. The genotyping was performed using tetra-primer amplification refractory mutation systems PCR. Results: Analysis of genotypes revealed that CYP24A1 rs4809960 CC genotype decreased the risk of CRC (p = 0.009). In addition, the genotype frequencies showed a significant difference under the dominant and recessive inheritance models (p = 0.019 and p = 0.02, respectively). Conclusion: Our findings indicate that the CYP24A1 rs4809960 polymorphism decreased the risk of CRC in the studied population.

Abstract
Cytochrome P450 family 24 subfamily A member 1 (CYP24A1) gene is overexpressed in many cancers including colorectal cancer (CRC) and correlated with tumor invasion, lymph node metastasis, and the reduced overall survival. We predicted that miR-30a and miR-125a regulate the CYp24A1 gene expression. Therefore, we performed a case-control study using 800 individuals, including 389 patients with CRC and 411 noncancer controls to evaluate the association between miR-30a rs2222722 and miR-125a rs12976445 polymorphisms, located at in the promoter region, and the risk of sporadic CRC in an Iranian population. The genotyping assay for both polymorphisms was performed using Tetra-primer amplification refractory mutation systems polymerase chain reaction. The results indicated that the frequency of the miR-30a rs2222722 CT genotype was significantly different in the studied groups ( P = 0.0001; odds ratio [OR] = 1.9; 95% confidence interval [CI], 1.39-2.60). Also, a significant difference was observed under the dominant inheritance model ( P = 0.0001; OR = 1.8; 95% CI, 1.33-2.43). The frequency of the miR-30a rs2222722 T allele was significantly associated with increased CRC risk in the studied population ( P = 0.0019; OR = 1.47; 95% CI, 1.15-1.89). Taken together, our study provides preliminary evidence that the rs2222722 polymorphism increases the susceptibility to CRC in an Iranian population. Therefore, the affecting factors on CYP24A1 gene expression such as microRNAs can be considered as risk factors for CRC.

Abstract
BACKGROUND The pathogenicity of acute myeloid leukemia (AML) is highly influenced by genetic alterations, such as chromosomal abnormalities. Additionally, aberrations in the mechanisms involved in gene expression have been identified to have a role in the development of AML. Contradictory evidence has been reported concerning the expression of the CEBPA gene in AML patients. Additionally, investigation into the expression of the CEBPA-AS gene has yet to be explored in AML patients. The aim of the present study was to investigate the relationship between the expression of the CEBPA and CEBPA-AS genes and AML in Iranian patients. METHODS Using quantitative real-time PCR, the expression of the CEBPA and CEBPA-AS genes was examined in the peripheral blood samples of 58 patients with de novo adult AML, and in 20 healthy controls. RESULTS Overall, CEBPA expression analysis showed a significant up-regulation in AML patients compared with healthy controls. Interestingly, a significant up-regulation of CEBPA was detected in the male AML patients. Significant CEBPA over-expression was observed in M0 (p-value=0.0001), M3 (p-value= 0.012) and M4 (p-value= 0.000) FAB subtypes. Our data has also demonstrated that CEBPA expression is up-regulated in favorable (p-value= 0.006) and adverse (p-value= 0.042) cytogenetic risk groups. In addition, the expression of CEBPA was significantly increased in AML patients with an abnormal karyotype. Ectopic expression of CEBPA-AS was detected in seven of the AML patients. CONCLUSION Our study provides evidence for the up-regulation of CEBPA and the ectopic expression of CEBPA-AS in AML patients, suggesting that these two genes may play an important role in the pathogenesis of AML. The role of CEBPA and CEBPA-AS in AML patients should be further explored. This will offer potential opportunities for the development of novel treatment strategies.

Abstract
Background: Preeclampsia is a hypertensive disorder that affects pregnancy, mother, and fetus. Pathogenesis of preeclampsia could be associated with the angiogenesis pathways. The vascular endothelial growth factor (VEGF) family is one of the important factors for normal pregnancy and angiogenesis. Genetic variations in the gene family members may play a role in the etiology of preeclampsia. We investigated the possible association between VEGFA gene rs3025039, and VEGFR1 (FLT1) gene rs722503 polymorphisms and preeclampsia in a sample of Iranian patients. Methods: Genotyping was performed in 395 women, including, 204 pre-eclamptic pregnant women and 191 healthy normotensive pregnant women by using the PCR-RFLP method. Results: The rs722503 polymorphism was associated with preeclampsia under the dominant model (P = 0.04, OR = 1.53, 95% CI: 1.03-2.27). No significant difference was observed for the rs3025039 alleles and genotypes in the studied groups. Conclusions: Based on our study, rs722503 polymorphism in the FLT1 gene may play an important role in susceptibility to preeclampsia.

Abstract
Purpose The aim of this study was to identify the molecular genetic basis of hereditary retinal dystrophies (HRDs) in five unrelated Iranian families. Methods Whole exome sequencing and Sanger sequencing were performed in all families. Variants were analyzed using various bioinformatics databases and software. Results Based on the selected strategies, we identified potentially causative variants in five families with HRDs: the novel homozygous deletion mutation c.586_589delTTTG (p.F196Sfs*56) in the TTC8 gene of family A, the novel homozygous missense mutation c.2389T>C (p.S797P) in the CRB1 gene in family B, the novel homozygous frameshift mutation c.2707dupA (p.S903Kfs*66) in the LRP5 gene in family C, the novel homozygous splice mutation c.584-1G>T in the MERTK gene in family D, and the novel homozygous missense mutation c.1819G>C (p.G607R) rs61749412 in the ABCA4 gene of family E. Conclusions This study highlights the presence of five novel variants associated with retinal dystrophies in selected Iranian families with hereditary blindness.

Abstract
This study aims to ascertain the genetic variants which contribute to the most common types of MPS in eleven Iranian families. Clinical and biochemical features were obtained during initial examination and patients were further investigated for genetic defects in the MPS genes. Peripheral blood samples were obtained from all family members after obtaining written informed consent. Based on the patient's clinical diagnosis, three different genetic tests including Sanger sequencing of four genes (IDUA, IDS, SGSH, and GALNS), targeted panel (10 genes) and Whole Exome Sequencing (WES) techniques were applied to identify the causative variants. A total of 12 different mutations were identified in five genes, including nine novel mutations and three previously reported missense mutations. Sanger sequencing confirmation of the identified mutations determined one case of compound heterozygous in the NAGLU gene. In this study, novel mutations in MPS related genes were identified attempting to characterize the type and subtype of the disease using molecular approaches. Results of the study positively contribute to mutation spectrum of IDUA, IDS, SGSH, NAGLU, and GALNS genes in the Iranian cohort. It may also enrich genetic counseling for rapid risk assessment and disease management.

Abstract
Breast cancer is the most common cancer in Iran. In the recent years an upward trend has been observed in the Iranian population. Early detection by molecular approaches may reduce breast cancer morbidity and mortality. We provided consultation to 3,782 women diagnosed with early onset breast cancer during the past 15 years (1999-2014). To establish a data set for BRCA gene alterations of the Iranian families at risk, two hundred and fifty four women who met our criteria were analyzed. A total number of 46 alterations including 18 variants with unknown clinical significance (39.1%), 18 missense mutations (39.1%), 7 Indels (15.2%) and 3 large rearrangement sequences (6%) were identified. Further scanning of affected families revealed that 49% of healthy relatives harbor identical causative mutations. This is the first report of comprehensive BRCA analysis in Iranian women with early onset breast cancer. Our findings provide valuable molecular data to support physicians as well as patients for the best decision making on disease management.

Abstract
We described the orthodontic treatment of a girl diagnosed with VWS. Multidisciplinary techniques resulted in satisfactory outcomes. Genetic testing determined a known putative splice site mutation.
Introduction Van der Woude syndrome (VWS) is the most frequent form of syndromic cleft lip and palate (SCLP) accounting for 2% of all patients with CLP. Case presentation We describe the orthodontic treatment of a girl diagnosed with VWS referred by her family dentist for her cosmetic concerns. Discussion Comprehensive orthodontic treatment, secondary bone graft, distraction osteogenesis (for a deficient maxilla), secondary palatoplasty and excision of lower lip pits, as well as orthodontic and prosthetic procedures may provide a satisfactory outcome. Genetic testing showed a known putative splice site mutation (c.174 + 1 G/A) as the prime cause of VWS in our patient and her family. Conclusion SCLP has significant effects on facial aesthetics and the psychosocial status. Parents should be assessed and counseled appropriately. This condition is treatable in the absence of life threatening systemic anomalies. An interdisciplinary team approach is advocated.

Abstract
Gene expression profiling has been suggested to predict breast cancer outcome. The prognostic value of the 8q22-24 position in breast cancer remains to be elucidated. The present study evaluated expression patterns of the genes located at this position in metastatic and non-metastatic breast cancer. A total of 85 patients with recurrent/metastatic (n=15) and non-metastatic (n=70) early-stage, estrogen receptor-positive and lymph node-negative breast tumors were included. In addition, 15 normal breast tissue samples were used as controls. Demographic and clinical features were recorded. Subsequently, mRNA copy numbers of exostosin glycosyltransferase 1 (EXT1), WNT1 inducible signaling pathway protein 1 (WISP1), ATPase family, AAA domain containing 2 (ATAD2), TSP-like 5 (TSPYL5), metadherin (MTDH) and cyclin E2 (CCNE2) genes were measured by reverse transcription-quantitative polymerase chain reaction assay. The expression of EXT1 and WISP1 exhibited a significant decline in the metastatic breast cancer group compared to the control (P=0.015 and P=0.012, respectively). The expression of TSPYL5, MTDH and ATAD2 was significantly decreased in the metastatic (P=0.002, P=0.018 and P=0.016, respectively) and non-metastatic (P=0.038, P=0.045 and P=0.000, respectively) breast cancer groups compared with the control. The expression of CCNE2 in the metastatic and non-metastatic breast cancer groups was significantly increased compared with the control (P=0.002 and P=0.001, respectively). WISP1 expression demonstrated a correlation with patient age and tumor size, and TSPYL5 expression was correlated with lymphovascular invasion. None of the genes investigated exhibited any correlation with stage and grade of disease. The TSPYL5, MTDH, ATAD2 and CCNE2 genes may be implicated in the pathogenesis of human breast cancer, while the WISP1 and EXT1 genes may have the potential to serve as promising indicators of the risk of metastasis. However, further studies are required to validate these results.

Abstract
Mucolipidosis type II α/β (ML II α/β) and mucolipidosis type III α/β (ML III α/β) have been shown to be caused by an absence or reduced level of uridine diphosphate (UDP)-N-acetylglucosamine-1-phosphotransferase enzyme (EC 2.7.8.17) activity, respectively. Both disorders are caused by mutations in the GNPTAB gene and are inherited in an autosomal recessive manner. Here we report a 2-year-old female patient being diagnosed as a case of ML II α/β due to coarse face, severe developmental delay, multiple dysostosis, noticeable increase of multiple lysosomal enzymes activity in plasma and normal acid mucopolysaccharides in urine. Mutational analysis of the GNPTAB gene has revealed a novel homozygous mutation in the patient (c.3250-2A>G) with both parents being heterozygote. Transcript analyses showed that this novel splice site mutation leads to exon 17 skipping and a frameshift afterwards (p.P1084_R1112del F1113Vfs*1). Consequently, we confirmed the association of this mutation with ML II α/β. Our finding expands the number of reported cases of this rare metabolic disorder and adds to the GNPTAB mutation database.

Abstract
Osteogenesis imperfecta (OI) is a set of clinically and genetically heterogeneous disorders with autosomal dominant, recessive and X-linked inheritance patterns. The aim of this study was to describe a novel genetic abnormality in a case of OI type XI with mild joint contractures, kyphoscoliosis, muscular atrophy, progressively deforming and multiple bone fractures in a consanguineous Iranian family. Based on the phenotype, investigation of two candidate genes, CRTAP (OI type VII) and FKBP10 (OI type XI) detected a novel homozygous frameshift mutation in the FKBP10 gene. This finding can be useful in accurate genetic counseling and prioritization of molecular analysis of OI in Iranian patients.

Abstract
Pantothenate kinase- associated neurodegeneration (PKAN) syndrome is a rare autosomal recessive disorder characterized by progressive extrapyramidal dysfunction and iron accumulation in the brain and axonal spheroids in the central nervous system. It has been shown that the disorder is caused by mutations in PANK2 gene which codes for a mitochondrial enzyme participating in coenzyme A biosynthesis. Here we report two cases of classic PKAN syndrome with early onset of neurodegenerative disorder. Mutational analysis has revealed that both are homozygous for a novel nonsense mutation in PANK2 gene (c.T936A (p.C312X)). The high prevalence of consanguineous marriages in Iran raises the likelihood of occurrence of autosomal recessive disorders such as PKAN and necessitates proper premarital genetic counseling. Further research is needed to provide the data on the prevalence of PKAN and identification of common PANK2 mutations in Iranian population.
