objective(s):familial mediterranean fever (fmf) is an autosomal recessive disorder characterized by recurrent episodes of fever accompanied by peritonitis, pleurisy, and arthritis. fmf affects mainly mediterranean populations and is caused by mutations in the familial mediterranean fever (mefv) gene. the aim of this study was to identify the frequency and distribution of mefv mutations in irani...

we studied 74 patients with lebers hereditary optic neuropathy (lhon) to investigate causative mtdna mutations (g3460a, g11778a, t14484c, g4459a) in iranian lhon patients. fifty two patients carried the mitochondrial dna (mtdna) g11778a mutation, while one had the t14484c mutation 4 patients had the g3460a mutation and one had the g14459a mutation. our results showed a similarity in the pattern...

BACKGROUND Multiple births occur frequently in some Iranian sheep breeds, while infertility scarcely occurs. Mutation detection in major fecundity genes has been explored in most of Iranian sheep flocks over the last decade. However, previously reported single nucleotide polymorphisms (SNPs) for bone morphogenetic protein receptor-(BMPR)-1B and growth differentiation factor ) GDF9( known to aff...

Anophthalmia or microphthalmia (A/M) is a rare group of congenital/developmental ocular malformations, characterized by absent or small eye within the orbit affecting one or both eyes. It  has complex etiology with chromosomal, monogenic with high heterogeneity, and environmental causes. We performed genome SNP-array analysis followed by autozygosity mapping and sequencing in the members o...

Introduction: Autosomal dominant polycystic kidney disease (ADPKD) is one of the most common genetic kidney disorders with the incidence of 1 in 1,000 births. ADPKD is genetically heterogeneous with two genes identified: PKD1 (16p13.3, 46 exons) and PKD2 (4q21, 15 exons). Eighty five percent of the patients with ADPKD have at least one mutation in the PKD1 gene. Genetic studies have demonstrate...

Hereditary ataxias are a clinically and genetically heterogeneous family of disorders defined by the inability to control gait and muscle coordination. Given the nonspecific symptoms of many hereditary ataxias, precise diagnosis relies on molecular genetic testing. To this end, we conducted whole-exome sequencing (WES) on a large consanguineous Iranian family with hereditary ataxia and oculomot...

Mutations in DPAGT1 are a newly recognised cause of congenital myasthenic syndrome. DPAGT1 encodes an early component of the N-linked glycosylation pathway. Initially mutations in DPAGT1 have been associated with the onset of the severe multisystem disorder - congenital disorder of glycosylation type 1J. However, recently it was established that certain mutations in this gene can cause symptoms...

DST encodes bullous pemphigoid antigen-1 (BPAG1), a protein with eight tissue-specific isoforms expressed in the skin, muscle, brain, and nerves. Accordingly, mutations this gene cause different phenotypes, including epidermolysis bullosa simplex (EBS) hereditary sensory autonomic neuropathy type VI (HSAN-VI). The genotype-phenotype correlation is attested to by 19 distinct but not well establi...
