Forty-nine members of a family with autosomal-dominant progressive sensorineural hearing loss were evaluated by audiologists, otologists, and geneticists. The results presented here show a nonsyndromic, autosomal-dominant mutation causing progressive sensorineural hearing loss beginning at about age 20 and becoming profound by approximately age 45. Because of the unambiguous nature of the hearing loss, the size of the family, and the availability of two previously described temporal bones from family members, a fairly complete description of the nature and impact of this mutation will be presented.
Key Words: hearing loss, genetic, autosomal dominant
