Investigations on the variability of four genetic serum protein markers in Poland.

Abstract

198 unrelated male and female Poles from Ostrów Wielkopolski (Central Poland) and 228 unrelated male and female Kashubes from Kościerzyna (Northern Poland) have been typed for four polymorphic serum protein systems: HP, TF, GC, and PI. Phenotype and allele frequencies of all these four polymorphic systems are quite different between Poles and Kashubes. Comparisons with some other Central and East European population samples (Slovaks, Hungarians, Matyos, Gypsies) revealed a considerable genetic heterogeneity among them. Genetic distance analysis showed that Hungarians and Matyos as well as Poles and Slovaks are found in two subclusters, which are linked up to one cluster. Gypsies and especially Kashubes exhibit a distinct position from this cluster. This genetic distance pattern can be explained satisfactorily considering the ethnohistory of the population groups under study.
