Hearing loss affects over a billion people globally, with many cases stemming from genetic factors. Among these, mutations in the GJB2 gene are prevalent in Caucasians, Asians, and Hispanics, while MYO15A and ATP6V1B1 mutations are common in Africa. Emerging treatments like gene therapy aim to correct these genetic defects. Chinese researchers recently reported success using Adeno-associated virus (AAV) vectors to deliver healthy OTOF genes to patients with hereditary deafness 9, resulting in significant hearing improvements.
