ABSTRACT
Objective To study the frequency of 9 bp sequence deletion of mithochondrial DNA in three ethnic nationalities of Guizhou Province .Methods A total of 183 male blood samples were randomly extracted from Miao nationality (69 cases) in Leishan County ,Shui nationality (44 cases) and Buyi nationality (70 cases) in Libo County .Polymerase chain reaction(PCR) and di-rect sequencing were used to detect the mithochondrial DNA 9 bp sequence deletion .Results The standard type ,deleting type and 3 type were found in the samples of 3 ethnic nationalities in Guizhou Province ,the highest deletion frequency was Shui nationality (40 .91% ) in Libo County ,1 cases of 3 type was detected in Miao nationality of Leishan County ,and the mtDNA 9 bp deletion fre-quency had no statistical difference among 3 ethnic nationalities(P>0 .05) .Conclusion The frequency of mtDNA 9 bp deletion is different among three native minorities ,the genetic variation in Shui nationality is larger ,compared with Miao nationality genetic re-lationship ,Shui nationality has a relatively closer affinity with Buyi nationality .
