- Abstract
- The adenomatous polyposis coli (APC), which is the susceptible gene for familial adenomatous polyposis (FAP) and sporadic colorectal cancer, spans 15 exons. The open reading frame of APC is 8529 bp, which encodes 2843 amino acids. Conventional genetic screening involves extensive time as well as high cost and labor. Thus, we developed a novel APC ready-to-use plate for high-throughput mutational analysis by denaturing high performance liquid chromatography (DHPLC). To prepare the ready-to-use APC plate, all 38 primer pairs and PCR mixtures were aliquoted into individual wells of a 96-well plate, and frozen at -20 degrees C until use. All 38 PCR primers were designed to be amplified at the same temperature (52 degrees C). We examined a total of 27 FAP patient samples with APC germline mutations (17 for multiple bp deletions, 1 for 1 bp deletion, 9 for nonsense mutations) and 50 APC-negative noncarriers. All 17 multiple bp deletion mutations were detected during the initial 50 degrees C running analysis and thus ruled out for further analyses. All other mutations were clearly detected under specific optimized conditions. More than 50% of the APC germline mutations were multiple base pair deletions and efficiently selected by omitting time-consuming partial denaturing conditions.
