Polymorphism of mitochondrial DNA region V in Bouyei people and Miao people living in Guizhou province of China / 中华医学遗传学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the polymorphism of mitochondrial DNA region V in Bouyei people and Miao people living in Guizhou province of China.</p><p><b>METHODS</b>Polymerase chain reaction and direct sequencing were used in the study.</p><p><b>RESULTS</b>Only two kinds of polymorphism were found in Bouyei and Miao people. One was standard pattern, the other short pattern. And the frequencies of short pattern(9 bp deletion) in Bouyei and Miao people were 31.1% and 33.3% respectively.</p><p><b>CONCLUSION</b>The polymorphisms of mitochondrial DNA region V in Bouyei people and Miao people living in Guizhou province of China are similar, but they are different from those in other people.</p>
