Involvement in diseasei

Deafness, autosomal recessive, 93 (DFNB93)1 Publication
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionA form of non-syndromic deafness characterized by stable, bilateral, symmetric, prelingual moderate to severe deafness. Hearing impairment is slightly more pronounced in the mid-frequencies, resulting in a distinctive shallow U-shaped audiogram.
