    [Show abstract] [Hide abstract] ABSTRACT: Adapter-ligation-mediated allele-specific amplification (ALM-ASA) is a potential method for multiplex SNPs typing at an ultra low cost. Here, we describe a kind of software, which designs allele-specific primers for ALM-ASA assay on multiplex SNPs. DNA sequences containing SNPs of interest are submitted into the software which contains various endonucleases for options. Based on the SNP sequence information and the selected endonucleases, the software is capable of automatically generating sets of information needed to perform genotyping experiments. Each set contains a suitable endonuclease, qualified allele-specific primers with orientations and melting temperatures, sizes of allele-specific amplicons, and gel electropherograms simulated according to the sizes of the allele-specific amplicons and the mobility of DNA fragments in 2% agarose gel. Seven SNPs in the arylamines N-acetyltransferase 2 (NAT2) gene, five SNPs in the BRCA1 gene, five SNPs in the COMT gene, six SNPs in the CYP2E1 gene, five SNPs in the MPO gene, and six SNPs in the NRG1 gene were selected for evaluating the software. Without extra optimization, seven SNPs in the NAT2 gene were successfully genotyped for genomic DNA samples from 127 individuals by using the first set of allele-specific primers yielded by the software. Although several steps are used in the ALM-ASA assay, the whole genotyping process can be completed within 3 h by optimizing each step. Profiting from the software, the ALM-ASA assay is easy-to-perform, labor-saving, and accurate.
