Relative Frequency of 35delG Mutation in GJB2 Gene in Autosomal Recessive Non-Syndromic Hearing Loss (ARNSHL) Patients in Kerman Population
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...
متن کاملConnexin 26 and autosomal recessive non-syndromic hearing loss
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...
متن کاملAutosomal recessive non-syndromic hearing loss in the Lebanese population: prevalence of the 30delG mutation and report of two novel mutations in the connexin 26 (GJB2) gene.
EDITOR—The most common sensory deficit in humans is hearing loss, aVecting 1 in 1000 children, with approximately half of the cases having a genetic cause. The majority of these genetic causes are non-syndromic, of which approximately 75% have an autosomal recessive mode of inheritance. So far, nearly 30 genes that cause non-syndromic recessive deafness (NSRD) have been located (for review see ...
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 کاملAnalysis of GJB2 (Connexin 26) Mutation in Patients with Congenital Non-Syndromic Sensorineural Hearing Loss
South European cases with autosomal recessive inherited hearing loss (4,8). The frequent incidence of the 35delG mutation requires analyzing both affected individuals and parents (in terms of being carriers) for genetic counseling. The aim of this study was to determine the frequency of GJB2 gene mutations in patients with congenital NSSNHL and to investigate new mutations of the GJB2 gene in o...
