Mitochondrial DNA polymorphism in Japanese (original) (raw)

Summary

Mitochondrial DNA (mtDNA) from 116 Japanese was analyzed with nine restriction enzymes that recognize a four or five base pair sequence. The sizes of the mtDNA fragments produced by digestion by each enzyme were compared after gel electrophoresis. Double digestion experiments indicated that, in the coding region from URF2 (unidentified reading frame) to tRNAAsn (bp 5274–5691), there is an insertion of about 60 base pairs (bp) compared with the published mtDNA sequence, which is common to all individuals in the present sample. A total of 95 different morphs were detected with the nine enzymes, 60 of which have not been documented previously. Based on a comparison of the cleavage maps of all individuals, 62 different combinations of restriction types were observed. By pairwise comparison of each restriction type, the average number of nucleotide substitutions per nucleotide site (δ) was estimated to be 0.0026. Phylogenetic analysis of the present data indicates that at least two distinct lineages exist in the Japanese population.
