HLA types, blood groups, serum protein and red cell enzyme types among Samoans in New Zealand.

101 Samoans living in New Zealand, of whom 77 had no known non-Samoan ancestry, have been typed for nine blood group systems, four serum protein and 23 red cell enzyme systems, for haemoglobin variants and antigens at the HLA A nad B loci. The frequencies of genes in these various systems suggest that Samoans fall partly into an island Melanesian-Micronesian pattern, and partly are unique. Their uniqueness is most distinctive for the HLA system.
