Nonsyndromic X-linked hearing loss.
To date, 135 loci and 50 genes have been identified as causes of nonsyndromic hearing loss. Until recently, four loci (DFN2, DFN3, DFN4, and DFN6) had been implicated in nonsyndromic X-linked hearing loss; however, a new classification (DFNX1-5) has been proposed to reduce confusion in the terminology. The different types of nonsyndromic X-linked hearing loss demonstrate various clinical featur...
متن کاملInherited nonsyndromic hearing loss. An audiovestibular study in a large family with autosomal dominant progressive hearing loss related to DFNA2.
OBJECTIVE To study nonsyndromic progressive sensorineural hearing loss (SNHL) with significant linkage to the DFNA2 locus on chromosome 1p in a Dutch kindred. DESIGN A 6-generation family with 194 family members was studied. Of the presumably affected persons, 43 were examined in detail to obtain audiograms and 37 underwent vestibulo-ocular examination. RESULTS Regression analysis showed si...
متن کاملAutosomal Recessive Nonsyndromic Hearing Loss: A Case Report with a Mutation in TRIOBP Gene
Hearing loss (HL) is the most common sensory defect. Various genetic as well as environmental factors have been shown to contribute in it. More than 100 loci have been recognized to cause autosomal recessive nonsyndromic hearing loss (ARNSHL). Here, we report a 6-year old female patient with bilateral pre-lingual HL in whom a mutation has been identified in TRIOBP gene (c.6362C>T, S2121L). In s...
متن کاملTwo Iranian families with a novel mutation in GJB2 causing autosomal dominant nonsyndromic hearing loss.
Mutations in GJB2, encoding connexin 26 (Cx26), cause both autosomal dominant and autosomal recessive nonsyndromic hearing loss (ARNSHL) at the DFNA3 and DFNB1 loci, respectively. Most of the over 100 described GJB2 mutations cause ARNSHL. Only a minority has been associated with autosomal dominant hearing loss. In this study, we present two families with autosomal dominant nonsyndromic hearing...
متن کاملA POU3F4 Mutation Causes Nonsyndromic Hearing Loss in a Chinese X-linked Recessive Family
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...
