Abstract

Otosclerosis is a common form of conductive hearing loss with a prevalence of 0.3–0.4% in white adults. It is characterized by labyrinthine endochondral sclerosis which may invade the stapedio-vestibular joint and interfere with free motion of the stapes. Both environmental factors and genetic causes have been implicated in the disease process; however, the pathogenesis of otosclerosis still remains poorly understood. To date, several loci have been mapped in families segregating autosomal dominant otosclerosis although no disease-causing mutations have been identified. In contrast, several association studies have implicated specific genes but their effects on risk-of-disease are small. The goal of this paper is to review the genetics of otosclerosis and to provide insight into studies that could be performed to elucidate disease pathogenesis.
