Investigation of the GJB6 Deletion Mutations Del (GJB6- D13s1830) and Del (GJB6-D13s1854) in Iranian Patients with Autosomal-Recessive Non-Syndromic Hearing Loss (ARNSHL)
Hearing loss (HL) is the most common inherited sensory disorder affecting about 1 in 1000 births. The first locus for nonsyndromic autosomal recessive HL is on chromosome 13q11–22. The two genes, GJB2 and GJB6, are closely located on chromosome and are known to be co-expressed in the embryonic cochlea. Deletion mutations involving GJB6 were associated with autosomal-recessive nonsyndromic heari...
متن کاملC.35delG/ GJB2 and del(GJB6-D13S1830) mutations in Croatians with prelingual non-syndromic hearing impairment
BACKGROUND C.35delG/GJB2 mutation is the most frequent genetic cause of deafness in Caucasians. Another frequent mutation in some Caucasian populations is del(GJB6-D13S1830). Both GJB2 and GJB6 genes belong to the same DFNB1 locus and when the two mutations are found in combination in a hearing-impaired person, a digenic pattern of inheritance is suggested. METHODS We examined 63 Croatian sub...
متن کاملAllele-Specific Impairment of GJB2 Expression by GJB6 Deletion del(GJB6-D13S1854)
Mutations in the GJB2 gene, which encodes connexin 26, are a frequent cause of congenital non-syndromic sensorineural hearing loss. Two large deletions, del(GJB6-D13S1830) and del(GJB6-D13S1854), which truncate GJB6 (connexin 30), cause hearing loss in individuals homozygous, or compound heterozygous for these deletions or one such deletion and a mutation in GJB2. Recently, we have demonstrated...
متن کاملبررسی موتاسیون های شایع ژن های GJB2 و GJB6 در مبتلایان به بیماری ناشنوایی غیرسندرومی اتوزومی مغلوب در منطقه‌ی آذربایجان شرقی
Background and Objective: Profound hearing loss is one of the most prevalent congenital disorders affecting about 1 in 1000 newborns. Autosomal recessive non-syndromic hearing loss (ARNSHL) is the predominant form of the severe inherited childhood deafness. This type of hearing loss in one-half of the cases is caused by mutations in GJB2 (connexin 26) and GJB6 (connexin 30) genes located at DFN...
متن کاملEvaluation 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...
