Gene Therapy Deafness

In this image from video provided by the Children’s Hospital of Philadelphia, an 11-year-old boy who was born with hereditary deafness is given a hearing test in Philadelphia, after he underwent a gene therapy procedure in October 2023. On Tuesday, Jan. 23, 2024, the hospital announced his hearing has improved enough that he now has only mild to moderate hearing loss in the ear that was treated, and is hearing sound for the first time in his life.
