Little did my parents realize that both of them were carriers of a genetic condition known as Usher’s syndrome, which is characterized by congenital deafness with progressive visual loss.
Minu vanematel polnud aimugi, et nad mõlemad kannavad geeniriket, mida nimetatakse Usheri sündroomiks, millele on iseloomulik kaasasündinud kuulmisnõrkus ja nägemise nõrgenemine.
