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 کاملMitochondrial gene mutation screening in hearing loss patients, Hormozgan, Iran
Introduction: Hearing loss is the most frequent sensory disorder occurs in 1/1000 newborns. About 50% of hearing loss cases are due to genetic causes. Mutation in MTRNR1(A1555G), MTTL1(A3243G) and MTTS1(A7445G) are known to be one of the important cause of nonsyndromic Sensorineural hearing loos in some populations. This study aims to demonstrate the frequency of three mitochondrial mutatio...
متن کاملThe association between GJB2 mutation and GJB6 gene in non syndromic hearing loss school children.
Recently, molecular testing for GJB2 mutations has become the standard of care for the diagnosis of patients with non syndromic hearing impairment of unknown cause. The aims of this study are to determine the association between GJB2 mutation and GJB6 and to report the variation of mutations in deaf students who have heterozygous GJB2. This retrospective study was conducted at Universiti Kebang...
متن کاملA novel C202F mutation in the connexin26 gene (GJB2) associated with autosomal dominant isolated hearing loss.
Mutations in the GJB2 gene encoding connexin26 (CX26) account for up to 50% of cases of autosomal recessive hearing loss. In contrast, only one GJB2 mutation has been reported to date in an autosomal dominant form of isolated prelingual hearing loss. We report here a novel heterozygous 605G-->T mutation in GJB2 in all affected members of a large family with late childhood onset of autosomal dom...
متن کاملA common founder for the 35delG GJB2 gene mutation in connexin 26 hearing impairment.
Fifty to eighty percent of autosomal recessive congenital severe to profound hearing impairment result from mutations in a single gene, GJB2, that encodes the protein connexin 26. One mutation of this gene, the 35delG allele, is particularly common in white populations. We report evidence that the high frequency of this allelic variant is the result of a founder effect rather than a mutational ...
