Abstract

The population structure of two alleles with similar characteristics, HbS and beta-thalassemia, was studied in the same area in Sicily. It was observed that beta-thalassemia has uniform frequencies over the island, and that HbS shows a South-North cline. A singularity exists for HbS in the town of Butera, where the frequency of the S gene is six times higher than the island average. It was suggested that HbS entered Sicily from Greece (or directly from North Africa) when the beta-thalassemia allele was already established in the Island
