Mitochondrial DNA polymorphisms in a sample of Albanian population (Tirana)

RFLPs of mtDNA for HpaI, BamHI, HaeII, MspI, AvaII and HincII were analysed in a sample of 100 from collected in Tirana (Albania). Eighteen mtDNA types were identified, four of which are new: two because of new morphs for Hpa/HincII (HpaI-9Tir/HincII-17Tir) and AvaII (AvaII-35Tir), and two because of new associations between morphs which were already known. Albanian data were compared with corresponding ones from Calabrians (Southern Italians) and Arbreshes (people of Albanian ancestry living in Calabria). Even though the examined mtDNA markers do not reveal important differences among the three groups, the analysis of both morphs and types shows a trend which places Arbreshes closer to Calabrians than to Albanians.
