On the variability of Gc subtypes in Italy

909 individuals from different places of Italy were analyzed for the distribution of Gc subtypes. The observed heterogeneity in the distribution of the allele frequencies was found to be statistically significant. Comparing our results with those reported by other authors it is seen that within Italy a considerable regional variation in the frequencies of the Gc subtype alleles is present. However, there are no indications for any particular distribution patterns or gradients. In one of our samples (Bari district), one case of Gc 1S-1C3 was found.
