The major symptoms of Usher syndrome are deafness or hearing loss and an eye disease called retinitis pigmentosa (RP) [re-tin-EYE-tis pig-men-TOE-sa]. Deafness or hearing loss in Usher syndrome is caused by abnormal development of hair cells (sound receptor cells) in the inner ear.
Is Usher syndrome a disability?
