Notes:
Serum specimens from local Whites, Blacks and Amerindians were phenotyped for the B subunit of Factor XIII. Isoelectric focusing of desialylated samples on agarose gels at a pH 4-7 gradient followed by an immunoblotting technique was used for band identification. Gene frequencies for the three common alleles in Whites, F XIII*1, F XIIIB*2 and F XIIIB*3 were 0.776, 0.088 and 0.136, respectively, and were consistent with reports on this genetic marker system in European Whites. The Blacks and Amerindians were clearly differentiated from the Whites with F XIIIB*1,2 and 3 frequencies of 0.286, 0.635 and 0.079, respectively, for Blacks and 0.500, 0.034 and 0.466 for Amerindians. Based on the available population data on Factor XIIIB, this genetic system should prove to be a valuable marker for anthropological genetics and parentage testing.
