Population data studies for TH01 and VWA were carried out on a Hungarian caucasian population sample of 244 unrelated individuals. We found 7 and 8 different alleles for TH01 and VWA, respectively. Using a high resolution/non-denaturing horizontal PAGE system no variations in the mobility of alleles were detected except for the allele 14 in VWA. The allele frequencies observed are similar to those reported in the literature for European caucasians. The genotype distributions meet Hardy-Weinberg expectations for both STR systems.
