The main options for people with hereditary hearing loss are hearing aids and cochlear implants. Both options have their limitations and do not restore biological hearing. Researchers want to learn if gene editing might be a treatment option.\n\nObjective:\n\nTo understand the genes that cause non-syndromic autosomal dominant hearing loss (DFNA) in people with DFNA as well as their family members.\n\nEligibility:\n\nPeople age 3 99 who have DFNA, affected family members of enrolled participants with DFNA, and unaffected family members of enrolled participants\n\nDesign:\n\nParticipants will be screened with a medical and hearing history. Their medical records will be reviewed.\n\nParticipants will have hearing tests. They will wear headphones or earplugs. They will listen to tones, sounds, and words and may be asked to describe what they hear.\n\nParticipants will have balance tests. For these, they will wear googles as they watch moving lights or as cold or warm air is blown into their ears. They will sit in a spinning chair in a quiet, dark booth. From a reclined position, they will raise their head while listening to clicking sounds.\n\nParticipants will have blood drawn through a needle in the arm. Some blood will be used for gene testing.\n\nSome participants will have 2 skin biopsies. The skin will be washed, and a numbing medicine will be injected. Two small pieces of skin will be removed.\n\nParticipants may have a physical exam.\n\nParticipation will last for up to 20 years. Participants may give medical updates once a year.",[68],"Hearing Loss",[70,71,72],"DFNA","Genome Editing","Natural History","2026-05-06",{"date":75,"type":76},"2026-05-07","ACTUAL",{"date":78,"type":76},"2021-02-09",{"date":80,"type":64},"2029-08-21",{"name":18,"class":6},1]
