Abstract

For purposes of genetic comparison, the available HLA data on United States and African Black, together with United States Caucasoid populations, are summarized. Antigen frequencies and pairwise linkage disequilibria are presented for the HLA‐A, ‐B and ‐C loci in Black populations typed for the 1975 Histocompatibility Testing Workshop. The Black population samples comprise 356 North American Blacks and 411 African Blacks of whom 222 were Bantu. These are compared with a sample of 503 American Caucasoids. All significant linkage disequilibria between the A and B loci found in North American Blacks were also present in the North American Caucasoids. Between the B and C loci, Bw35 and Cw4 were in strong linkage disequilibrium in all groups. Significantly strong association between the A and C loci (Aw28 with Cw3) were observed only in the African Blacks. There were unique disequilibria both in the American Caucasoids and African Blacks. Although the frequencies of many antigens in U.S. Blacks lie between those in Africans and U.S. Caucasoids, there are exceptions such as Aw33, Bw35, Cw4.
