Evaluation of GJB2 and GJB6 Mutations in Patients Afflicted with Non-syndromic Hearing Loss
Background Non-syndromic hearing loss (NSHL) is assumed as one of the highly prevalent congenital defects in the world. In this regard, gap junction protein beta 2(GJB2), and gap junction protein beta 6(GJB6) mutations are considered as the leading congenital causes of deafness. The present study aimed to assess the prevalence of GJB2 and GJB6 mutations in NSHL cases. Materials and Methods This...
متن کاملRelative frequency of GJB2 gene mutations in autosomal recessive non-syndromic hearing loss (ARNSHL) patients in Lorestan population
Background: Congenital hearing loss due to different 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. Materials and methods: The aim of this study was to study the frequency of GJB2 Mutations in Lor...
متن کاملContribution of connexin26 (GJB2) mutations and founder effect to non-syndromic hearing loss in India.
Congenital hearing loss has been documented to occur in 1 of 1000 live births, with over half of these cases predicted to be hereditary in nature. 2 Most hereditary hearing loss is inherited in a recessive manner, accounting for approximately 85% of non-syndromic hearing loss (NSHL). Deafness is an extremely genetically heterogeneous disorder, shown by the fact that 33 loci for recessive NSHL a...
متن کاملStudy of frequency and spectrum of GJB2 gene mutations in non-syndromic hearing loss patients of Semnan province
Abstract Background and aim: The frequency of hearing impairment is one out of 500 newborn babies, worldwide. However, in Iran, due to the high prevalence of consanguineous marriages, this amount is estimated to be two to three times higher. So far, more than 120 genes causing non-syndromic Hearing loss (NSHL) have been identified in the world, of which GJB2 gene mutations are the most common c...
متن کاملGJB2 and SLC26A4 gene mutations in children with non-syndromic hearing loss in Southern China
Non-syndromic hearing loss (NSHL) is a major public health issue and affects a substantial proportion of newborns worldwide. Currently little information is available about the molecular etiology of hearing impairment in the Chinese population. Therefore, this study aimed to perform a comprehensive investigation on the genetic mutation patterns of non-syndromic deafness in Zhongshan City, a cit...
