The DFNB1 subtype of autosomal recessive non-syndromic hearing impairment.
Inherited hearing impairment is a frequent and highly heterogeneous condition. Among the different subtypes of autosomal recessive non-syndromic hearing impairment, DFNB1 is remarkable for its high frequency in most populations. It is caused by mutations in the coding region or splice-sites of the GJB2 gene, or by mutations affecting regulatory sequences that are essential for the expression of...
متن کاملPrevalence of mitochondrial DNA mutations in childhood/congenital onset non-syndromal sensorineural hearing impairment.
Genetic factors are the major causes of childhood hearing impairment. Whereas autosomal recessive mutations account for the majority of prelingual non-syndromic sensorineural hearing impairment (NSSHI), the relative contribution of mitochondrial DNA (mtDNA) mutations to childhood onset NSSHI has not been established. We screened 202 subjects with congenital/childhood onset NSSHI, consisting of ...
متن کاملMapping of a new autosomal dominant non-syndromic hearing loss locus (DFNA43) to chromosome 2p12.
Hearing impairment (HI) is the most frequent sensory defect with wide genetic heterogeneity. Approximately 80% of genetic hearing loss is non-syndromic and 15-25% of exhibit autosomal dominant inheritance. We analysed an Italian three generation family in which non-syndromic hearing impairment is transmitted as an autosomal dominant trait. Onset of HI in all affected subjects occurred in the se...
متن کاملA new autosomal recessive retinitis pigmentosa locus maps on chromosome 2q31-q33.
Autosomal recessive retinitis pigmentosa (ARRP) is a genetically heterogeneous disease. To date, mutations in four members of the phototransduction cascade have been implicated in ARRP. Additionally, linkage of the disease to three loci on 1p, 1q, and 6p has been described. However, the majority of cases are still uncharacterised. We have performed linkage analysis in a large nuclear ARRP famil...
متن کاملInvestigation of LRTOMT gene (locus DFNB63) mutations in Iranian patients with autosomal recessive non-syndromic hearing loss
Hearing loss (HL) is the most frequent sensory defect affecting 1 in 1000 neonates. This can occur due to genetic or environmental causes or both. The genetic causes are very heterogenous and over 100 loci have been identified to cause autosomal recessive non - syndromic hearing loss (ARNSHL). The aim of this study was to determine the contribution of the LRTOMT gene mutations in causing ARNSHL...
