Exploring mitochondrial DNA variation in the Italian Peninsula

Summary:The genetic structure of Italy appears to be mainly shaped by pre-Roman historical events. The studies carried out so far show a major North–South cline, possibly the result of two distinct main demic processes: the first colonisation of the area during the Palaeolithic period and the subsequent Neolithic expansion from the Middle East. However, the demographic contribution of these events is still a matter of debate. We here report mitochondrial DNA (mtDNA) data from nine population groups covering the main Italian regions: Central Liguria ( N = 50), East Friuli ( N = 51), South Latium ( N = 48), Central Marche ( N = 53), West Calabria ( N = 50), Central Campania ( N = 50), South Apulia ( N = 53), and two populations from Sicily (East and West Sicily, N = 40 each). Haplogroup frequency spectra indicate clear differences at a regional level and haplotype sharing among populations is low.
