HLA and non-HLA phenotyping and genotyping in Austral and Gambier Polynesian Archipelagos

Forty-one individuals from Rurutu Island (Austral Archipelagos) and 41 individuals from the Gambier Archipelagos have been typed for HLA; for blood groups ABO, Rh, MNSs, P, Kell, Kp, Lewis, Lutheran, Kidd; for the electrophoretic systems G6PD, 6-PGD, PGM1, PGM2, AcP, ADA, GPT, Est-D, GLO I, and for the immunoglobulin allotypes Gm and Km. There is a high degree of homogeneity among these Polynesian populations and among other Polynesian populations previously typed. However, small differences exist between the populations of the two archipelagos, possibly due to endogamy or to the smallness of the samples studied. A variant of HLA-Bw22 (called Bw22x) is described.
