Sensorineural hearing loss, striate palmoplantar hyperkeratosis, and knuckle pads in a patient with a novel connexin 26 (GJB2) mutation.
M utations in connexin 26 (GJB2, Cx26) cause autosomal recessive and occasionally dominant non-syndromic sensorineural hearing loss (SNHL). Cx26 mutations have also been identified in SNHL with dermatological features of autosomal dominant diffuse palmoplantar hyperkeratosis (DPPK). We describe a girl with bilateral sloping sensorineural hearing loss, striate palmoplantar hyperkeratosis (SPPK),...
متن کاملPseudoexfoliation Syndrome and Sensorineural Hearing Loss
Introduction: Pseudoexfoliation syndrome (PXS) occurs due to the deposition of extracellular fibrillar materials on the anterior chamber of the eye. This syndrome has been considered to be part of a systemic disease with the potential involvement of the inner ear called sensoroneural hearing loss (SNHL). In this study, we aimed on evaluating SNHL within PXS patients in Iran to compare them wi...
متن کاملConnexin 26 studies in patients with sensorineural hearing loss.
OBJECTIVE To determine the spectrum of connexin 26 (Cx26) mutations and their phenotypes in children with sensorineural hearing loss (SNHL) or mixed hearing loss (MHL). DESIGN Children with SNHL or MHL were prospectively tested for mutations in the entire coding region of the Cx26 gene. PATIENTS Children with SNHL or MHL with no obvious etiology for the hearing loss. RESULTS Between Decem...
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...
متن کاملFamilial leuconychia, knuckle pads, hearing loss, and palmoplantar hyperkeratosis: an additional family with Bart-Pumphrey syndrome.
A family with five members who have variable findings of leuconychia, knuckle pads, hearing loss, and palmoplantar hyperkeratosis is described. The findings in these subjects are compared with those noted in previously reported patients with Bart-Pumphrey syndrome. The range of disorders which include knuckle pads as part of the phenotype is reviewed.
