Hearing is normal without connexin30.
Gjb2 and Gjb6, two contiguous genes respectively encoding the gap junction protein connexin26 (Cx26) and connexin 30 (Cx30) display overlapping expression in the inner ear. Both have been linked to the most frequent monogenic hearing impairment, the recessive isolated deafness DFNB1. Although there is robust evidence for the direct involvement of Cx26 in cochlear functions, the contribution of ...
متن کاملATP8B1 is essential for maintaining normal hearing.
ATP8B1 deficiency is caused by autosomal recessive mutations in ATP8B1, which encodes the putative phospatidylserine flippase ATP8B1 (formerly called FIC1). ATP8B1 deficiency is primarily characterized by cholestasis, but extrahepatic symptoms are also found. Because patients sometimes report reduced hearing capability, we investigated the role of ATP8B1 in auditory function. Here we show that ...
متن کاملIs Sudden Hearing Loss Associated with Atherosclerosis?
Introduction: Sudden sensorineural hearing-loss (SSNHL) patients constitute approximately 2–3% of referrals to ear, nose and throat (ENT) clinics. Several predisposing factors have been proposed for this condition; one of which is vascular disorders and perfusion compromise. In this research the atherosclerotic changes and their known risk factors are studied in SSNHL patients. Materials and ...
متن کاملA Novel Missense Mutation in the Connexin30 Causes Nonsyndromic Hearing Loss
Dysfunctional gap junctions caused by GJB2 (CX26) and GJB6 (CX30) mutations are implicated in nearly half of nonsyndromic hearing loss cases. A recent study identified a heterozygous mutation, c.119C>T (p.A40V), in the GJB6 gene of patients with nonsyndromic hearing loss. However, the functional role of the mutation in hearing loss remains unclear. In this study, analyses of cell biology indica...
متن کاملA connexin30 mutation rescues hearing and reveals roles for gap junctions in cochlear amplification and micromechanics
Accelerated age-related hearing loss disrupts high-frequency hearing in inbred CD-1 mice. The p.Ala88Val (A88V) mutation in the gene coding for the gap-junction protein connexin30 (Cx30) protects the cochlear basal turn of adult CD-1Cx30A88V/A88V mice from degeneration and rescues hearing. Here we report that the passive compliance of the cochlear partition and active frequency tuning of the ba...
