Congenital Deafness And Piebaldness In Two American Indians.


Congenital deafness and piebaldness (partial albinism) occur in 2 male Hopi siblings. A brother and their parents are normal. Subtotal nerve deafness occurs in both siblings. A striking feature is the uniformity in depigmentation pattern in both even though they differ in age by 4 years. From available data there is no way of determining whether this gene, recessive in nature, is located on the X chromosome or an autosome. Photos. Line graphs. Bibliography.
