Biallelic Mutations in the Gap Junction Beta 2 (GJB2) Gene Clinical Trial
Official title:
A Retrospective and Prospective Natural History Study to Examine the Characteristics of Gene-Related Hearing Loss in Pediatric Participants With Biallelic Otoferlin (OTOF) Mutations, Gap Junction Beta 2 (GJB2) Mutations, Or Digenic GJB2/Gap Junction Beta 6 (GJB6) Mutations
This is an observational study to examine the characteristics of gene-related hearing loss in pediatric participants with biallelic otoferlin (OTOF) Mutations, Gap Junction Beta 2 (GJB2) Mutations, or Digenic GJB2/Gap Junction Beta 6 (GJB6) Mutations. This study will follow the participant for 4 years with annual visits each year.
Former Sponsor Decibel Therapeutics This is a longitudinal, retrospective and prospective, low interventional study designed to collect data on the natural history of pediatric participants with OTOF, GJB2, or GJB2/GJB6 gene mutations to assess hearing-related outcomes, auditory skills, and speech perception. No investigational product will be administered. At study visits, participants will undergo physiological and behavioral assessments of hearing and vestibular function. Additionally, parents/legal guardians or participants will complete questionnaires that will include the capture of epidemiologic, quality-of-life, auditory and language development, and health resource utilization information. ;
