Several populations were typed for the hypervariable region II (HVRII) of the mitochondrial DNA (mtDNA) control region using immobilised sequence-specific oligonucleotide (SSO) probes. A total of 16 SSO probes was used to type 1081 individuals from eight different ethnic groups (African Americans, Somali, US Europeans, US Hispanics, Bosnians, Finns, Saami and Japanese). Data was compared with already published sequence data by analysis of principal components, genetic distances and analysis of the molecular variance (AMOVA). The analyses performed group the samples in several clusters according to their geographical origins. Most of the variability detected is assigned to differences between individuals and only 7% is assigned to differences among groups of populations within and between geographical regions. Several features are patent in the samples studied: Somali, as a representative East African population, seem to have experienced a detectable amount of Caucasoid maternal influence; different degrees of admixture in the US samples studied are detected; Finns and Saami belong to the European genetic landscape, although Saami present an outlier position attributable to a strong maternal founder effect. The technique used is a rapid and simple method to detect human variation in the mtDNA HVRII in a large number of samples, which might be useful in forensic and population genetic studies.
