Limited genetic diversity in polynesians reflected in the highly polymorphic 3'HVR alpha-globin gene marker.
Polynesians from five distinct island groups were studied with DNA probe alpha 3'HVR, a highly polymorphic VNTR (variable number of tandem repeats) minisatellite region associated with the alpha-globin gene cluster. Results showed a paucity of genetic heterozygosity together with clustering of alpha 3'HVR alleles with alpha-globin DNA haplotypes and alpha-globin gene rearrangements. This restricted diversity is consistent with population bottlenecks in the colonization of Polynesia.
