Genetic polymorphisms of six Y chromosome short tandem repeat loci in Chinese Korean ethnic group / 中华医学遗传学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To determine the allelic sequences and genetic polymorphism of six short tandem repeats (STRs) loci on Y chromosome, including DYS441, DYS442, DYS443, DYS444, DYS445 and DYS446 in Chinese Korean ethnic males from Yanbian region of Jilin province, China, and to construct a preliminary database.</p><p><b>METHODS</b>Allele frequencies of the six STR loci in 205 Chinese Korean ethnic individuals were analyzed by multiplex polymerase chain reaction (PCR) and polyacrylamide gel electrophoresis (PAGE).</p><p><b>RESULTS</b>Respectively, 8, 7, 7, 5, 6 and 9 alleles were detected for each of the locus. Together they have formed 151 haplotypes, with a diversity of 0.9937.</p><p><b>CONCLUSION</b>The six STR loci included in this study were found to be highly polymorphic, and may provide useful markers for genetic analysis.</p>
