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).;
