Abstract

The mitochondrial DNA HV3 region contains CA dinucleotide repeats which display length polymorphism. To analyze this for forensic purposes, we designed a fluorescence-labelled PCR primer set for short amplification products and carried out genotyping by using capillary electrophoresis. A total of 4 alleles with 4–7 repeat units were observed and the genetic diversity was estimated to be 0.5120 in 500 unrelated Koreans. Interestingly, three individuals showed two or three length variants, i.e. length heteroplasmy.
