Abstract
60 patients with different ethiopathogenic non-syndromic sensoryneural hearing loss were screened for A1555G point mutation in 12s ribosomal RNA gene of mitochondrial DNA, a reason for hereditary non-syndromic hearing loss. Mutation were found in two patients (∼3,3%) with different phenotypic hearing loss: aminoglycoside ototoxicity in the adult age and sensoryneural hearing loss without a clear ethiology from childhood. In both cases we noticed nonsyndromic, postlingual, bilateral, symmetricand progressive sensory neural hearing loss of III-IV degree. As well as the presence of hearing impairment in blood relatives. Similar mutation in mitochondrial gene as a cause different phenotypic variants of sensory neural hearing loss was studied among various ethnic groups and was revealed for the first time among population of the europion region of Russia.
