Genetic analysis of the STR system D20S161 in Japanese and Bangladeshi

The allele distributions of the STR locus D20S161 have been investigated in Japanese and Bangladeshi people. No deviation from the Hardy-Weinberg equilibrium was observed in either population. D20S161 was found to be a polymorphic STR with seven alleles in Japanese and with six alleles in Bangladeshi. The distribution of allele frequencies in Japanese was very similar to that in Bangladeshi. The D20S161 system can be a potential marker for medicolegal individualization and paternity testing.
