title: Immunoglobulin haplotypes of two population groups in Iran.
abstract: Genetic markers of IgG and IgA were investigated in two population groups from Iran. The Gm-Am haplotypes found were mainly those prevalent in Caucasians, with a low frequency of Asiatic haplotypes. Twenty samples had phenotypes that led to the assumption of rare haplotypes. The main ones were: Gm(z;n;b)a2m(1) and Gm(za;n;g)A2m(2). The first haplotype differs from the common haplotypes because G1m(z) is present instead of G1m(f), and the second because it has G2m(n) and A2m(2) in combination with G1m(za) and G3m(g).
