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 ...
Autosomal recessive nonsyndromic hearing loss (ARNSHL) is the most common form of congenitally acquired inherited hearing impairment. Although numerous loci are believed to exist, only five have been identified. Using a pooled genomic DNA screening strategy, we have identified a sixth locus, DFNB6, on 3p in the interval bounded by D3S1619 and D3S1766.
Sensorineural hearing loss (SNHL) is a heterogeneous family of hearing disabilities with congenital (including genetic) as well as acquired etiology. Congenital SNHL of genetic etiology is further sub-divided into autosomal dominant, autosomal recessive and X-linked SNHL. More than 60 genes are involved in the etiology of autosomal recessive non-syndromic hearing loss (ARNSHL) commonly manifest...
Abstract Background Autosomal recessive non-syndromic hearing loss (ARNSHL) is genetically and phenotypically heterogeneous with over 110 genes causally implicated in syndromic loss. Here, we investigate the genetic etiology of deafness two GJB2 GJB6 negative patients presenting pre-lingual, progressive, severe Methods Targeted exome sequencing (TES) using Next Generation Illumina Sequencing wa...
The incidence of pre-lingual hearing loss (HL) is about 1 in 1000 neonates. More than 60% of cases are inherited. Non-syndromic HL (NSHL) is extremely heterogeneous: more than 130 loci have been identified so far. The most common form of NSHL is the autosomal recessive form (ARNSHL). In this study, a cohort of 36 big ARNSHL pedigrees with 4 or more patients from 7 provinces of Iran was investig...

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...
OBJECTIVES Non-syndromic sensorineural hearing loss (NSHL) is a common disorder affecting approximately 1 in 500 newborns. This type of hearing loss is extremely heterogeneous and includes over 100 loci. Mutations in the GJB2 gene have been implicated in about half of autosomal recessive non-syndromic hearing loss (ARNSHL) cases, making this the most common cause of ARNSHL. For the latter form ...
Hearing loss is one of the most common sensorineural defects in humans. Autosomal-recessive nonsyndromic hearing loss (ARNSHL) is the most frequent form among inherited forms of deafness and accounts for greater than 70% of the cases. Due to extreme genetic heterogeneity of ARNSHL, many known loci have to be screened to find linkage to deafness genes or before proceeding to a genome wide analys...
Hereditary hearing loss is characterized by a high degree of genetic heterogeneity. Mutations in the TMPRSS3 (transmembrane protease, serine 3) gene cause prelingual (DFNB10) or postlingual (DFNB8) deafness. In our previous study, three pathogenic mutations in TMPRSS3 were identified in one Chinese family. To evaluate the importance of TMPRSS3 mutations in recessive deafness among the Chinese, ...
