Immunoglobulin (Ig) allotypes are polymorphic genetic systems that show distinct racial arrays, thus making them powerful tools for studies of genetic admixture and biological relationships. In the province of Sorsogon, southern Luzon, Philippines, allotyping was completed on 252 persons residing in two neighboring villages. The people demonstrated 14 GM and 3 KM phenotypes. The frequency of homozygous KM3, KM1 and heterozygous KM1,3 was identical in these villages; however, half of the GM phenotypes present in one village were significantly less frequent in the other village. The frequency of KM and GM haplotypes was different from those reported in Filipino aboriginal groups, but similar to a population on Samar Island, the only other Filipino group for which Ig allotype data exist. Variability in the prevalence of parasitic disease such as lymphatic filariasis may in part reflect differences in genetic susceptibility, resulting from allotypic heterogeneity between villages.
