Un grand espoir pour les personnes atteintes de surdités héréditaires.

For the first time in history, scientists have restored hearing in people born deaf by fixing a single faulty gene through viral gene therapy. This breakthrough is giving hope to millions living with hereditary hearing loss.
The therapy works by delivering a corrected version of the defective gene directly into the cells of the inner ear. This gene is essential for producing proteins that allow sound waves to be translated into electrical signals for the brain. Once restored, patients who had never heard a sound began recognizing speech, music, and environmental noises.
Early trials, especially in young children, showed dramatic improvements in speech recognition and auditory response. This is significant because the brain adapts most quickly during early development, making gene therapy particularly effective in younger patients.
Beyond restoring hearing, this success demonstrates the vast potential of gene therapy to correct other congenital conditions. It represents a major step toward curing genetic diseases rather than managing them, and may one day make hereditary deafness a preventable condition.
