[Polymorphisms of 9 short tandem repeat loci in Chinese subjects of Li nationality in Hainan Province].

Objective: To obtain the data of the genotypes and allele frequencies of 9 short tandem repeat (STR) foci (D18S1364, D12S391, D13S325, D6S1043, D2S1772, D11S2368, D22-GATA198B05, D8S1132, and D7S3048) in Chinese subjects of Li and Han nationalities in Hainan Province.

Methods: A total of 154 randomly selected unrelated subjects of Li nationality and 112 unrelated local Han subjects from Hainan Province, along with 125 Han subjects recent immigrated to Hainan were enrolled in this investigation. Venous blood samples were obtained from the subjects to determine the allele frequencies at the 9 STR loci using multiplex primer extension assay.
