title: The HumD21S11 system of short tandem repeat DNA polymorphisms in Japanese and Chinese.
abstract: HumD21S11 is a short tandem repeat DNA polymorphic system with a complex basic structure of (TCTA)4-6 (TCTG)5-6 (TCTA)3 TA (TCTA)3 TCA (TCTA)2 TCCA TA (TCTA)n. Using the allelic ladder prepared by us, the distribution of alleles among Japanese and Chinese was investigated, and four new alleles 28.2, 34, 35.2, and 36.2, were discovered. DNA sequencing was performed on the newly found alleles as well as on family samples and led to the discovery of different gene structures within alleles 28 and 32. Forensic materials, including hairs and seminal stains, were tested in parallel with blood samples from the same individual and were successfully typed for D21S11.
