چکیده مقاله:

Objective(s) Despite the enormous heterogeneity of genetic hearing loss, most non-syndromic hearing losses are caused by mutations in the GJB2 gene. We aimed to characterize the mutation profiles of 100 Iranian deaf patients that were under 10 years old. Materials and Methods Patients were tested with direct sequencing of entire coding region of the GJB2 gene. Results Eight known mutations plus one novel (358delGAG) were found in 25% of study group. The 35delG mutation (64%) constituted the majority of GJB2 mutations. Conclusion Role of GJB2 mutation in Iranian young deaf population is more prominent than previous study that can be a result of higher consanguine marriage in population. But our result shows that there is only 25% non- syndromic hearing loss due to high frequency of consanguine marriage in Iranian population. Identification of other genes involved in genetic deafness will help us understand the fundamental mechanisms of normal hearing, both in early diagnosis and therapy.

Two Iranian families with a novel mutation in GJB2 causing autosomal dominant nonsyndromic hearing loss.

Mutations in GJB2, encoding connexin 26 (Cx26), cause both autosomal dominant and autosomal recessive nonsyndromic hearing loss (ARNSHL) at the DFNA3 and DFNB1 loci, respectively. Most of the over 100 described GJB2 mutations cause ARNSHL. Only a minority has been associated with autosomal dominant hearing loss. In this study, we present two families with autosomal dominant nonsyndromic hearing...

"two novel mutations and predominant 35delg mutation in the connexin 26 gene (gjb2) in iranian populations"

mutations in the gjb2 gene encoding connexin 26 (cx26) protein are a major cause for autosomal recessive non syndromic and sporadic deafness in many populations. in this study we have investigated the prevalence of the gjb2 gene mutations using nested pcr pre screening strategy and direct sequencing method. two hundred and sixty autosomal recessive non syndromic and sporadic deaf subjects from ...

Specific Distribution of GJB2 Mutations in Kurdistan Province of Iran; Report of a Relatively Isolated Population

Hearing Loss (HL) represents high genetic heterogeneity with an incidence of almost 1 out of 500 newborns in most populations. Approximately half of the cases have a genetic basis that most of them are autosomal recessive non-syndromic (ARNSHL) with DFNB1-related defect in many worldwide populations. Given the heterogeneity of the trait together with the unique infrastructure of Iranian populat...

Three Novel Mutations in Iranian Patients with Tay-Sachs Disease

Background: Tay-Sachs disease (TSD), or GM2 gangliosidosis, is a lethal autosomal recessive neurodegenerative disorder, which is caused by a deficiency of beta-hexosaminidase A (HEXA), resulting in lysosomal accumulation of GM2 ganglioside. The aim of this study was to identify the TSD-causing mutations in‌ an Iranian population. Methods: In this study, we examined 31 patients for TSD-causing m...

Detection of the GJB2 Mutation in Iranian Children with Hearing Loss Treated with Cochlear Implantation

The 35delG mutation in the gap junction protein, β2, 26kDa (GJB2) gene is the most common mutation that has been found in children with non syndromic hearing loss. Testing for the GJB2 gene mutation is simple and can directly answer the concerns of the parents about cause of the disorder and prognosis for their children. Cochlear implantation (CI) is one of the methods of hearing rehabilitation...
