Characterizing early-onset hearing loss related to genetic mutations

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

Observational Sensorion · NCT06354010

This study looks at how hearing loss develops in adults with genetic changes in the GJB2 gene to better understand their condition and track their hearing over time.

What this trial studies

This observational study focuses on patients with adulthood-onset bilateral sensorineural hearing loss, specifically those carrying mutations in the GJB2 gene. It aims to characterize the evolution of hearing impairment in these individuals and assess their genetic profiles. Participants will undergo genotyping and audiological assessments to gather comprehensive data on their condition. The study will also include a follow-up period for those identified with GJB2 mutations.

Who should consider this trial

Good fit: Ideal candidates are adults aged 30 to 55 with bilateral hearing loss that began after age 16 and have documented GJB2 mutations.

Not a fit: Patients with deafness due to known non-genetic causes will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to better understanding and management of genetic hearing impairments in adults.

How similar studies have performed: While studies on genetic causes of hearing loss exist, this specific focus on adulthood-onset presbycusis and GJB2 mutations is relatively novel.
