The molecular etiology of nonsyndromic sensorineural hearing loss (SNHL) in subjects with only one detectable autosomal recessive GJB2 mutation is unclear. Here, we report GJB2 single heterozygotes with various final genetic diagnoses and suggest appropriate diagnostic strategies. A total of 160 subjects with SNHL without phenotypic markers were screened for GJB2 mutations. Single-nucleotide va...
Mutations in GJB2 (gap junction protein, beta-2) are the major cause of autosomal recessive non-syndromic hearing loss. A few allele variants of this gene also cause autosomal dominant non-syndromic hearing loss as a dominant-negative consequence of expression of the mutant protein. Allele-specific gene suppression by RNA interference (RNAi) is a potentially attractive strategy to prevent heari...
A variant in a transcription factor gene, POU4F3, is responsible for autosomal dominant nonsyndromic hereditary hearing loss, DFNA15. To date, 14 variants, including a whole deletion of POU4F3, have been reported to cause HL in various ethnic groups. In the present study, genetic screening for POU4F3 variants was carried out for a large series of Japanese hearing loss (HL) patients to clarify t...
BACKGROUND The molecular genetic research showed the association between X-linked hearing loss and mutations in POU3F4. This research aimed to identify a POU3F4 mutation in a nonsyndromic X-linked recessive hearing loss family. METHODS A series of clinical evaluations including medical history, otologic examinations, family history, audiologic testing, and a high-resolution computed tomograph...
P rogressive hearing loss is a significant problem in all ageing populations. By the age of 80 years, nearly 50% of individuals have hearing loss that impairs their ability to communicate easily, leading to increasing social isolation. Progressive hearing loss in middle and late adulthood is considered multifactorial, with involvement of both genetic and environmental factors. In contrast, chil...
Several conditions fit this description, the mode of transmission being X-linked, autosomal dominant or recessive. The hearing loss is usually progressive and can be conductive, sensory or neural. In addition, some of the progressive inherited hearing losses of childhood may not develop auditory difficulties until adult life, although they should have been diagnosed in childhood (see Volume 6)....
RATIONALE Alström syndrome is an autosomal recessive disorder characterized by hearing loss, blindness, obesity, non-insulin dependent diabetes, and others. PATIENT CONCERN A 10 years old Saudi girl, who presented with diabetic ketoacidosis and found to have hearing loss and blindness. DIAGNOSIS Alström syndrome. INTERVENTIONS Multidisciplinary team approach, with echocardiography, hearin...
