Population genetic analysis of 15 STR loci of Chinese Tu ethnic minority group

We studied and established a DNA database of 15 euchromosorne STRs (D8S1179, D21S11, D7S820, CSF1PO, D3S1358, TH01, D13S317, D16S539, D2S1338, D19S433, vWA, TPOX, D18S51, D5S818 and FGA) in a population sample of 151 unrelated individuals of Tu ethnic minority group. Allelic frequencies and statistical parameters of Tu population were calculated. Totally 136 alleles were observed, with the corresponding allelic frequencies ranging from 0.0033 to 0.5359. Chi-square test showed that all STR loci agreed with Hardy-Weinberg equilibrium. Our study population data were compared with the previously publishing population data of other ethnic groups or areas. Our results of present study were valuable for human identification and paternity tests in Chinese Tu population. (C) 2007 Published by Elsevier Ireland Ltd.
