title: Rapid detection of sequence polymorphisms in the human mitochondrial DNA control region by polymerase chain reaction and single-strand conformation analysis in mutation detection enhancement gels.
abstract: The article describes a rapid approach for the detection of sequence polymorphisms in the mitochondrial (mt)DNA control region that involves enzymatic amplification of each entire mtDNA control region (HV1 and HV2) and the subsequent analysis of the PCR products by single-strand conformation analysis (SSCA) in mutation detection enhancement (MDE) gels, followed by silver stain detection. HV1 and HV2 SSC reference ladders were developed to standardize the classification of the different mtDNA types. Twenty-five mtDNA types were observed among the 45 Spanish individuals analyzed: 11 types were observed in the HV1 region as compared with 10 types in the HV2 region. This mutation scanning strategy could be a promising method of potential use not only in forensic genetics but also in population and evolutionary studies.
