Genetic Polymorphisms of STR Loci THO1、TPOX、CSF1PO in Guizhou Han Population
贵州地区汉族人群THO1、TPOX、CSF1PO基因座的遗传多态性 Genetic Polymorphisms of STR Loci THO1、TPOX、CSF1PO in Guizhou Han Population

To understand the genetic polymorphism at THO1,TPOX,CSF1PO STR loci for Han population in Guizhou Province,and construct a preliminary database,EDTA-blood specimens were collected from the 110 unrelated individuals in Han population from Guizhou.The DNA samples were extracted with Chelex method and amplified by multiplex polymerase chain reaction.The PAGE was used to type the PCR products.The allele frequencies were compared with other Han populations.The genotype distributions of THO1,TPOX and CSF1PO were in accordance with Hardy-Weinberg equilibrium.The combined PD and PE were 0.9986 and 0.832 respectively.All of the three loci in this study provide useful marker for forensic paternity test and individual identification.
