Tracking hearing loss in children with specific genetic mutations
Official title: Longitudinal Study of the Natural History of Two Autosomal Recessive Non Syndromic Deafness (DFNB1A and DFNB9) in Children up to 16 Years of Age
Run by Sensorion · NCT05402813 · Data updated 2026-11-12
This study is tracking children with hearing loss caused by specific genetic mutations to see how their condition changes over time and how it affects their quality of life.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are children aged 16 years or younger with documented mutations in the GJB2 or OTOF genes and bilateral sensorineural hearing loss.
✕Probably not a fit
Patients with other types of deafness, such as unilateral deafness or syndromic deafness linked to different genetic mutations, may not benefit from this study.

What this trial studies
This observational study follows children up to 16 years old who have mild to profound hearing loss due to mutations in the GJB2 or OTOF genes. It aims to describe the prevalence and types of mutations associated with DFNB1A and DFNB9, and to assess the clinical course of the disease. Participants will undergo pure tone audiometry assessments and complete quality of life questionnaires to gather comprehensive data on their audiological and genetic characteristics. The study will help differentiate between congenital and evolutive forms of hearing loss in these children.
Why it matters
Potential benefit: If successful, this study could enhance understanding of genetic hearing loss, leading to improved management and treatment strategies for affected children.
How similar studies have gone: Other studies have shown success in understanding genetic causes of hearing loss, making this approach promising but still requiring further exploration.
