Abstract
Hereditary spastic paraplegia (HSP) is a clinically and genetically heterogeneous neurodegenerative disorder, characterized by lower-limb spasticity and weakness. To date, more than 82 loci/genes (SPG1-SPG82) have been identified that contribute to the cause of HSP. Despite the use of next-generation sequencing-based methods, genetic-analysis has failed in the finding of causative genes in more than 50% of HSP patients, indicating a more significant heterogeneity and absence of a given phenotype-genotype correlation. Here, we performed whole-exome sequencing (WES) to identify HSP-causing genes in three unrelated-Iranian probands. Candidate variants were detected and confirmed in the probands and co-segregated in the family members. The phenotypic data gathered and compared with earlier cases with the same sub-types of disease. Three novel homozygous variants, c.978delT; p.Q327Kfs*39, c.A1208G; p.D403G and c.3811delT; p.S1271Lfs*44, in known HSP-causing genes including ENTPD1, CYP7B1, and ZFYVE26 were identified, respectively. Intra and interfamilial clinical variability were observed among affected individuals. Mutations in CYP7B1 and ZFYVE26 are relatively common causes of HSP and associated with SPG5A and SPG15, respectively. However, mutations in ENTPD1 are related to SPG64 which is an ultra-rare form of HSP. The research affirmed more complexities of phenotypic manifestations and allelic heterogeneity in HSP. Due to these complexities, it is not feasible to show a clear phenotype-genotype correlation in HSP cases. Identification of more families with mutations in HSP-causing genes may help the establishment of this correlation, further understanding of the molecular basis of the disease, and would provide an opportunity for genetic-counseling in these families.

Abstract
Human post-natal neurodevelopmental delay is often associated with cerebral alterations that can lead, by themselves or associated with peripheral deficits, to premature death. Here, we report the clinical features of 10 patients from six independent families with mutations in the autosomal YIF1B gene encoding a ubiquitous protein involved in anterograde traffic from the endoplasmic reticulum to the cell membrane, and in Golgi apparatus morphology. The patients displayed global developmental delay, motor delay, visual deficits with brain MRI evidence of ventricle enlargement, myelination alterations and cerebellar atrophy. A similar profile was observed in the Yif1b knockout (KO) mouse model developed to identify the cellular alterations involved in the clinical defects. In the CNS, mice lacking Yif1b displayed neuronal reduction, altered myelination of the motor cortex, cerebellar atrophy, enlargement of the ventricles, and subcellular alterations of endoplasmic reticulum and Golgi apparatus compartments. Remarkably, although YIF1B was not detected in primary cilia, biallelic YIF1B mutations caused primary cilia abnormalities in skin fibroblasts from both patients and Yif1b-KO mice, and in ciliary architectural components in the Yif1b-KO brain. Consequently, our findings identify YIF1B as an essential gene in early post-natal development in human, and provide a new genetic target that should be tested in patients developing a neurodevelopmental delay during the first year of life. Thus, our work is the first description of a functional deficit linking Golgipathies and ciliopathies, diseases so far associated exclusively to mutations in genes coding for proteins expressed within the primary cilium or related ultrastructures. We therefore propose that these pathologies should be considered as belonging to a larger class of neurodevelopmental diseases depending on proteins involved in the trafficking of proteins towards specific cell membrane compartments.

Abstract
Background The X chromosome has historically been one of the most thoroughly investigated chromosomes regarding intellectual disability (ID), whose etiology is attributed to many factors including copy number variations (CNVs). Duplications of the long arm of the X chromosome have been reported in patients with ID, short stature, facial anomalies, and in many cases hypoplastic genitalia and/or behavioral abnormalities. Methods Here, we report on a large Iranian family with X‐linked ID caused by a duplication on the X chromosome identified by whole genome sequencing in combination with linkage analysis. Results Seven affected males in different branches of the family presented with ID, short stature, seizures, facial anomalies, behavioral abnormalities (aggressiveness, self‐injury, anxiety, impaired social interactions, and shyness), speech impairment, and micropenis. The duplication of the region Xq13.2q13.3, which is ~1.8 Mb in size, includes seven protein‐coding OMIM genes. Three of these genes, namely SLC16A2, RLIM, and NEXMIF, if impaired, can lead to syndromes presenting with ID. Of note, this duplicated region was located within a linkage interval with a LOD score >3. Conclusion Our report indicates that CNVs should be considered in multi‐affected families where no candidate gene defect has been identified in sequencing data analysis.

Abstract
Autosomal recessive (AR) gene defects are the leading genetic cause of intellectual disability (ID) in countries with frequent parental consanguinity, which account for about 1/7th of the world population. Yet, compared to autosomal dominant de novo mutations, which are the predominant cause of ID in Western countries, the identification of AR-ID genes has lagged behind. Here, we report on whole exome and whole genome sequencing in 404 consanguineous predominantly Iranian families with two or more affected offspring. In 219 of these, we found likely causative variants, involving 77 known and 77 novel AR-ID (candidate) genes, 21 X-linked genes, as well as 9 genes previously implicated in diseases other than ID. This study, the largest of its kind published to date, illustrates that high-throughput DNA sequencing in consanguineous families is a superior strategy for elucidating the thousands of hitherto unknown gene defects underlying AR-ID, and it sheds light on their prevalence.

Abstract
Exploring genes and pathways underlying intellectual disability (ID) provides insight into brain development and function, clarifying the complex puzzle of how cognition develops. As part of ongoing systematic studies to identify candidate ID genes, linkage analysis and next-generation sequencing revealed Zinc Finger and BTB Domain Containing 11 (ZBTB11) as a novel candidate ID gene. ZBTB11 encodes a little-studied transcription regulator, and the two identified missense variants in this study are predicted to disrupt canonical Zn2+-binding residues of its C2H2 zinc finger domain, leading to possible altered DNA binding. Using HEK293T cells transfected with wild-type and mutant GFP-ZBTB11 constructs, we found the ZBTB11 mutants being excluded from the nucleolus, where the wild-type recombinant protein is predominantly localized. Pathway analysis applied to ChIP-seq data deposited in the ENCODE database supports the localization of ZBTB11 in nucleoli, highlighting associated pathways such as ribosomal RNA synthesis, ribosomal assembly, RNA modification and stress sensing, and provides a direct link between subcellular ZBTB11 location and its function. Furthermore, given the report of prominent brain and spinal cord degeneration in a zebrafish Zbtb11 mutant, we investigated ZBTB11-ortholog knockdown in Drosophila melanogaster brain by targeting RNAi using the UAS/Gal4 system. The observed approximate reduction to a third of the mushroom body size-possibly through neuronal reduction or degeneration-may affect neuronal circuits in the brain that are required for adaptive behavior, specifying the role of this gene in the nervous system. In conclusion, we report two ID families segregating ZBTB11 biallelic mutations disrupting Zn2+-binding motifs and provide functional evidence linking ZBTB11 dysfunction to this phenotype.

Abstract
BACKGROUND Knowledge of the genes responsible for intellectual disability, particularly autosomal recessive forms, is rapidly expanding. Increasing numbers of the gene show great heterogeneity and supports the hypothesis that human genome may contain over 2000 causative genes with a critical role in brain development. METHODS Since 2004, we have applied genome-wide SNP genotyping and next-generation sequencing in large consanguineous Iranian families with intellectual disability, to identify the genes harboring disease-causing mutations. The current study paved the way for identification of responsible genes in two unrelated Iranian families. RESULTS We found two novel nonsense mutations, p.C77* and p.Q115*, in the calpain catalytic domain of CAPN10, which is a cysteine protease known to be involved in pathogenesis of noninsulin-dependent diabetes mellitus. Another different mutation in this gene (p.S138_R139ins5) has previously been reported in an Iranian family. All of these patients have common clinical features in spite of specific brain structural abnormalities on MRI. CONCLUSIONS Different mutations in CAPN10 have already been found in three independent Iranian families. These results have strongly supported the possible role of CAPN10 in human brain development. Altogether, we proposed CAPN10 as a promising candidate gene for intellectual disability, which should be considered in diagnostic gene panels.

Abstract
BACKGROUND The genetic basis of longevity is an important field of study because the majority of supercentenarian cases experience healthy aging and may only show age-related diseases in their last few years of life. It is clear that genetic factors play an important role in survival beyond 90 years of age, but the exact relationship of genetic variants to this phenomenon remains unknown. OBJECTIVE The aim of this project was to investigate different hypotheses that describe the relationship between genetic variants and human longevity in a living Iranian man by Whole Exome Sequencing. METHODS Initially, we conducted high quality DNA extraction on a peripheral blood sample. Then, whole exome sequencing was performed on the DNA and different bioinformatic software packages and databases were used to analyze the data. Tertiary analysis was performed on four genetic hypotheses for longevity. RESULTS Analysis showed that among 27 metabolic variants which are related to longevity, 18 variants encompassed the exceptional longevity allele. In comparison with the NHGRI GWAS catalog, the case had 58 trait-associated variants of which 11 were homozygous for the risk allele. We also discovered 25 novel variants within candidate genes for aging and longevity and we detected seven longevity-associated variants in the sample. CONCLUSION This study was performed on just one sample and so the results cannot be interpreted as a generalized principle for other elderly societies, but this is the first step towards investigation of the genetic basis of longevity in Iran and provides an insight for further studies in the field of longevity.
