Cross-sectional and Prospective Study to Characterize Early-onset Presbycusis

Summary

The purpose of this study is to characterize and assess the evolution of hearing impairment of patients with adulthood-onset bilateral sensorineural hearing loss carrying mutations on GJB2 gene.

Detailed Description

This study aims to characterize patients with adulthood-onset bilateral sensorineural hearing loss not due to any underlying medical condition (likely due to a genetic cause) and to assess the evolution of hearing impairment of those carrying mutations in GJB2 gene. Patients who present with adulthood-onset bilateral sensorineural hearing loss will be screened for the presence of mutation involved in hearing impairment. Patients with GJB2 mutations will be proposed to continue in a follow-up period.
