[The genetic polymorphisms of 6 short tandem repeat loci in native Han population in Jiangxi province].
OBJECTIVE
To investigate the genetic polymorphisms of 6 short tandem repeats (STR) loci, namely, D6S1043, D2S1772, D7S3048, D22-GATA198B05, D8S1132 and D11S2368 in native Han population of Jiangxi province, China.


METHODS
Two hundred and twelve blood samples of unrelated subjects of Han population in Jiangxi province were collected. Genotyping was performed by using multiplex polymerase chain reaction-polyacrylamide gel electrophoresis.


RESULTS
Thirteen alleles and 52 genotypes in the D6S1043 locus, 13 alleles and 66 genotypes in D2S1772, 12 alleles and 48 genotypes in D7S3048, 11 alleles and 44 genotypes in D22-GATA198B05, 10 alleles and 38 genotypes in D8S1132, 10 alleles and 41 genotypes in D11S2368 locus, were detected in the 212 subjects. The observed heterozygosity (h) in D6S1043, D2S1772, D7S3048, D22-GATA198B05, D8S1132 and D11S2368 loci ranged from 0.8019 to 0.8774. The expected heterozygosity (H) varied from 0.8553 to 0.8896. The discriminating power (DP) ranged from 0.9559 to 0.9735. The probability of exclusion (PE) ranged from 0.7053 to 0.7751. The polymorphism information content (PIC) varied from 0.8452 to 0.8774.


CONCLUSIONS
All the 6 loci were of Hardy-Weinberg equilibrium. The genetic polymorphism of the 6 STR loci in Han population of Jiangxi province was high. The allelic distribution data at the 6 loci are valuable in population study, individual identification and paternity test for this population.
