Quizplus · Accepted Answer

The syndrome described is characteristic of Usher syndrome, a genetic disorder that affects both hearing and vision. It is caused by mutations in genes that are necessary for the normal development and function of the inner ear and retina, leading to hearing loss and progressive degeneration of the retina, resulting in retinitis pigmentosa. The symptoms typically begin with hearing loss in childhood, followed by vision loss in adolescence or early adulthood.
