title: Occurrence of the immunoglobulin haplotypes Gm1,17;23;21 and Gm1,2,17;23;21 in a sample of Australian Caucasians.
abstract: Phenotypes positive for G2m(23) but negative for G1m(3) and G3m(5,10,11,13,14) are generally very infrequent in Caucasian populations. We recently Gm typed 372 Australian blood donors, predominantly of European descent, and found two Gm(1;23) and five Gm(1,2;23) individuals among them. This finding suggests that the haplotypes Gm1,17;23;21 and Gm1,2,17;23;21 may occur, in some European populations, with a frequency considerably higher than has been generally assumed.
