[Mitochondrial DNA coding region 3954-4506 polymorphism in Korean Chinese population].
ABSTRACT To investigate the sequence polymorphism of mtDNA coding region encompassing nt3954-4506 in the Korean Chinese population of Yanbian area.
Polymerase chain reaction (PCR) and direct sequencing method were used to detect the haplotype distribution of mtDNA coding region in 198 Korean Chinese individuals.
Twenty-one haplotypes were observed in the 198 unrelated individuals. The genetic diversity was 0.5906 and the random match probability was 0.4124. Compared with the Andersonos sequence, 19 nucleotide variants were found, of which 14 were previously registered in MITOMAP, and 5 were novel.
The obtained data suggest that these sequence polymorphisms are valuable genetic markers for personal identification when combined with mtDAN control region investigation, thus could be used as basic data for the forensic application in Korean Chinese population.
