In this study, we define the variations of HV1 and HV2 of 517 unrelated Vietnamese individuals in Kinh, Muong, Cham, and Khmer ethnic. We found 50 haplogroups: F1a haplogroup frequency is the highest at 15.7%; B5a haplogroup frequency is 10.8%, M haplogroup frequency is 8.9%, M7b1 haplogroup frequency is 7.7%; B6, D4e, D5a, E, F1c, F2a, F3a, G2a, M9b, N, N21 and U5a haplogroup frequencies are the lowest (1%). The frequency of SNP A263G are 100%; A73G is 99.6%, 315insC is 96%; 309insC is 56%; C16223T is 41%, and T16189C is 39%. We have assessed the genetic polymorphism of mtDNA HV1 and HV2 of 517 Kinh, Muong, Cham, Khmer ethnic samples. ER -
