Molecular Epidemiology and Functional Assessment of Novel Allelic Variants of SLC26A4 in Non-Syndromic Hearing Loss Patients with Enlarged Vestibular Aqueduct in China
BACKGROUND Mutations in SLC26A4, which encodes pendrin, are a common cause of deafness. SLC26A4 mutations are responsible for Pendred syndrome and non-syndromic enlarged vestibular aqueduct (EVA). The mutation spectrum of SLC26A4 varies widely among ethnic groups. To investigate the incidence of EVA in Chinese population and to provide appropriate genetic testing and counseling to patients with...
متن کاملEnlarged vestibular aqueduct in congenital non-syndromic sensorineural hearing loss in egypt.
To estimate the frequency of isolated enlarged vestibular aqueduct (EVA) in patients with non-syndromic sensorineural hearing loss (SNHL) in an Egyptian population sample and to correlate its size with the degree of hearing loss. The study group comprised 16 patients (32 ears) suffering from non-syndromic SNHL since childhood. After a complete basic audiological evaluation, all patients were su...
متن کاملA Family of H723R Mutation for SLC26A4 Associated with Enlarged Vestibular Aqueduct Syndrome
Recessive mutations of the SLC26A4 (PDS) gene on chromosome 7q31 can cause sensorineural deafness with goiter (Pendred syndrome, OMIM 274600) or NSRD with goiter (at the DFNB4 locus, OMIM 600791). H723R (2168A>G) is the most commonly reported SLC26A4 mutations in Korean and Japanese and known as founder mutation. We recently experienced one patient with enlarged vestibular aqueduct syndrome. Th...
متن کاملVestibular pathology in children with enlarged vestibular aqueduct.
OBJECTIVES/HYPOTHESIS To establish the prevalence of abnormal vestibular test findings in children with enlarged vestibular aqueduct (EVA) and determine if these findings correlate with clinical symptoms, radiographic findings (EVA size and laterality), audiometric findings, and genetic testing in these patients. STUDY DESIGN Prospective cohort. METHODS Patients 3 to 12 years of age with he...
متن کاملSubgroups of enlarged vestibular aqueduct in relation to SLC26A4 mutations and hearing loss.
OBJECTIVES/HYPOTHESIS To investigate possible association of hearing loss and SLC26A4 mutations with the subgroups of enlarged vestibular aqueduct (EVA) morphology in Japanese subjects with hearing loss. STUDY DESIGN Retrospective multicenter study. METHODS Forty-seven subjects who had vestibular aqueduct with midpoint diameter >1 mm by computed tomography of the temporal bone were enrolled...
