    Abstract:
    OBJECTIVE: To develop a multiplexed mutagenically separated PCR (MS-PCR) for single nucleotide polymorphism (SNP) loci typing in mitochondrial DNA coding regions and to study the applications in investigating the allele frequencies and haplotypes of four SNP loci in mitochondrial DNA coding regions in Chinese Chengdu Han population. METHODS: Four SNP loci C12705T, A8701G, G8584A and C10400T, two allele specific forward primer with 4 bases different in size and a common reverse primer were designed for SNP typing. The primers simultaneously were amplified in a single tube. The genotyping of SNPs was determined by the two allele specific fragments different in size after polyacrylamide gel and silver staining. RESULTS: The different SNP loci comprised a single band with different size respectively. Typing results were completely consistent with those by direct sequencing. The allelic frequencies of C12705T, A8701G, G8584A and C10400T were 0.3813/0.6187, 0.4813/0.5187, 0.8250/0.1750 and 0.4938/0.5062 respectively. A total of 6 different haplotypes was identified and the genetic diversity reached 0.7137. CONCLUSION: Multiplexed MS-PCR is a simple, rapid, accurate and efficient method for SNP typing, which will be very powerful for SNPs in the database establishing of mitochondrial DNA coding regions, the testing of forensic and population genetics research.
