Deafness, autosomal dominant, 65
A form of non-syndromic sensorineural hearing loss. Sensorineural deafness results from damage to the neural receptors of the inner ear, the nerve pathways to the brain, or the area of the brain that receives sound information. DFNA65 is characterized by post-lingual onset of slowly progressive hearing loss in the third decade. Initially affecting the high frequencies, the hearing loss eventually affects all frequencies and results in severe to profound deafness in the seventh decade. Vestibular function is normal.
