Huntington's chorea in a black family: a report of 2 cases.
Two cases of Huntington's chorea occurring in a Black family are presented. One patient had, in addition, an arteriovenous anomaly of the cerebral circulation. The genealogy of the family is described and the probability of mixed descent is noted. The impression gained from the literature that Huntington's chorea rarely occurs in Blacks is strengthened.
