A collaborative genetic study on the STR system FGA in two Austrian population samples.

Population genetic data of the short tandem repeat system FGA were determined by PCR analysis in two Austrian population samples, one population north of the Alps and one population south of the Alps. A total of 15 different alleles could be observed in 500 unrelated individuals. No significant differences were found between the phenotype frequencies in the two populations, as determined by R x C contingency test, so the populations could be pooled for further analysis. Both the single populations and the pooled population are in accordance with Hardy-Weinberg equilibrium. FGA proves to be very efficient for both stain analysis and paternity testing. The presented allele and genotype data allow the statistical interpretation of this system for Austrians.
