" /> Deafness, nonsyndromic sensorineural, mitochondrial - CISMeF





Preferred Label : Deafness, nonsyndromic sensorineural, mitochondrial;

Type : Phenotype, molecular basis known;

Description : Mutations in mitochondrial DNA (mtDNA) have been found to be associated with nonsyndromic sensorineural hearing loss. Matrilineal relatives within and among families carrying certain pathogenic mitochondrial mutations exhibit a wide range of penetrance, severity, and age of onset of hearing loss, indicating that the mitochondrial mutations by themselves are not sufficient to produce a deafness phenotype. Modifier factors, such as nuclear and mitochondrial genes, or environmental factors, such as exposure to aminoglycosides, appear to modulate the phenotypic manifestations (summary by Tang et al., 2007).;
