G1m(a) and G1m(x) allotype distribution in a population from Calabria (Italy)

G1m(a) and G1m(x) allotype distribution is analyzed in a sample population from Calabria (South Italy). The paper presents data showing an unusually high frequency of the G1m(x) marker. Furthermore, results concerning a rare Gm(x) phenotype are also shown. The findings suggest the important contribution yielded to the Calabrian genetic pool by the Albanian population that immigrated to this region in the 15th century.
