HL‐A Types in Danish Eskimos from Greenland

Abstract

HL‐A typing of 110 Danish Eskimos has shown a marked difference in the frequencies of some HL‐A antigens as compared to Danish Caucasians. The most striking finding was a high frequency of HL‐A9, Ba*(W28), HL‐A5, BB (W10), and FJH(W27). There was a low frequency of HL‐A1, Li(<W19), HL‐A7, HL‐A8, and HL‐A12. This must result in a rather high chance for occurrence of the same HL‐A haplotypes in Eskimo matings, and the importance of this in relation to the high frequency of trophoblastic lesions among Eskimos is discussed.
