Abstract
To investigate the mitochondrial DNA (mtDNA) five coding region sequence polymorphisms encompassing positions nt3954-4506, nt5218-5974, nt7942-8711, nt10296-10653, and nt14496-14867 in Chinese Han population of Yanbian area, Jilin province. Polymerase chain reaction (PCR) and direct sequencing method were used to detect the haplotype distribution of mtDNA coding region in 200 unrelated Chinese Han individuals. One hundred and ten haplotypes were observed in the 200 individuals. The gene diversity was 0.9879 and the random match probability was 0.0171. Compared with the Anderson's sequence,81 nucleotide variants were obtained,of which 66 were previously registered in MITOMAP,and 15 were novel. The obtained data suggest that these sequence polymorphisms are valuable genetic markers for personal identification when added to mtDAN control region investigation, and thus could be used as basic data for the forensic application in Chinese Han population.
