Genetic polymorphism of fifteen short tandem repeat loci in Chinese Drungs / 中华医学遗传学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the short tandem repeat (STR) polymorphism in Chinese Drungs (Tulungs).</p><p><b>METHODS</b>The genetic distributions of fifteen STR loci were investigated with the use of coamplification, genescan and genotype from 67 Drungs.</p><p><b>RESULTS</b>There were 144 STR alleles in Drung nationality, with their frequencies ranging from 0.0077 to 0.7846, heterozygosity(H) 0.3723-0.8639, discrimination power(DP) 0.5567-0.9548, probability of paternity exclusion(EPP) 0.2738-0.8358, polymorphism information content (PIC) 0.3461-0.8456 the accumulative DP 0.99999998 and EPP 0.99999894.</p><p><b>CONCLUSION</b>The results of this study on the STR polymorphism in Chinese Drungs could be used as a basis for the genetic structure of Chinese ethnic groups and also be of significant application in anthropology and forensic science.</p>
