Genetic structure of western Sicily

The distribution of AB0, RH, KELL, ADA, GLO1, AK, 6PGD, ESD, ACP, G6PD, C3, GC and APOB markers were studied in a sample coming from the province of Trapani (western Sicily, Italy). The results were discussed in the contest of the Mediterranean populations. Our analysis confirms the existence of a certain genetic differentiation within Sicily and suggests a strong heterogeneity between our sample and the North African populations. Moreover our data point out the genetic affinity among Sicily, Southern Italy and Greece.
