The frequency of inherited bilateral autosomal recessive non-syndromic hearing loss (ARNSHL) in Pakistan is 1.6/1000 individuals. More than 50% of the families carry mutations in GJB2 while mutations in MYO15A account for about 5% of recessive deafness. In the present study a cohort of 30 ARNSHL families was initially screened for mutations in GJB2 and MYO15A. Homozygosity mapping was performed...
background: hearing loss (hl) is the most frequent sensory birth defect in humans. autosomal recessive non-syndromic hl (arnshl) is the most common type of hereditary hl. it is extremely heterogeneous and over 70 loci (known as dfnb) have been identified. this study was launched to determine the relative contribution of more frequent loci in a cohort of arnshl families. methods: thirty-seven i...
It has long been recognized that heredity plays a major role in hearing impairment. Although the facts about the genetic basis of hearing loss have fascinated both clinicians and geneticists for a long time, it is only within the last few years that the genes and molecular mechanisms underlying deafness have begun to be discovered. There is a great deal of genetic heterogeneity in deafness. Thi...
Congenital hearing loss with many genetic and environmental causes affects 1 in 1000 newborns. Mutations in the GJB2(Gap Junction Beta-2) gene encoding the gap junction protein connexin 26 have been established as the main cause of autosomal recessive non-syndromic hearing loss. The aim of this study was to study the frequency of one mutation (35delG) of GJB2 gene in Kerman non-syndromic deaf p...
OBJECTIVE Hereditary hearing impairment is a genetically heterogeneous disorder. In spite of this, mutations in the GJB2 gene, encoding connexin 26 (Cx26), are a major cause of nonsyndromic recessive hearing loss in many countries and are largely dependent on ethnic groups. The purpose of our study was to characterize the type and prevalence of GJB2 mutations among Azeri population of Iran. M...
Background Autosomal recessive non-syndromic hearing loss (ARNSHL) a most frequent hereditary type of hearing impairment, exhibit tremendous genetic heterogeneity. We aimed to determine the contribution of three common DFNB loci (DFNB4, DFNB28, and DFNB93), and mutation analysis of Gap Junction Beta-2 gene (GJB2) and GJB3 genes in ARNSHL subjects in southern Iran. Methods Thirty-six large ARN...
