deafness autosomal dominant type 6(redirected from DFNA6)
deafness autosomal dominant type 6A form of sensorineural hearing loss (OMIM:600965) due to damage to neural receptors of the inner ear, nerve pathways to the brain, or the auditory cortex. In DFNA6, perception of lower frequency (< 2000 Hz) sound is affected. Many patients also have tinnitus, but no vestibular symptoms (such as vertigo). Because high-frequency hearing is generally preserved, patients retain speech comprehension. DFNA6 worsens over time without progressing to profound deafness.
Defects of WFS1, which encodes a transmembrane protein that regulates Ca2+ homeostasis, cause deafness autosomal dominant type 6.
