Assistance Publique - Hôpitaux de Paris·observational·Posted Dec 17, 2019·Updated Feb 13, 2026

In Brief

An observational study evaluating Data collection and Genetic analysis for Congenital Profound Hearing Loss. Completed, enrolled 150 participants across 1 site.

Detailed Summary

Evaluation of a cohort of deaf children looking for autosomal recessive deafness-9 (DFNB9). Clinical and audiologic evaluation of patients with known auditive neuropathy / auditory dys-synchrony (ANAD) or recently diagnosed congenital severe to profound hearing loss (HL), and assessing genetic analysis looking for DFNB9. The investigators expect to compile genotypic and phenotypic characterization of 25 children with DFNB9 within 4 years.
