In the last few years genetic identification and paternity testing have begun to make increasing use of autosomal SNP (Single Nucleotide Polymorphism) typing as a supplement or alternative to STR analysis. With the improvement in detection technology SNP analysis is likely to be easier and more sensitive, with the generation of new methods and multiplex systems for a growing array of SNP markers. SNPforID consortium developed 52 SNP PCR multiplex for human identification purposes detected with 23 plex and 29 plex single base extension reactions (Auto1 and 2 respectively). In this study, internal validation for the 29 SNPs of Auto2 was carried out by performing a 29 plex PCR and single base extension reaction on control samples and previously analyzed forensic casework and subsequent detection with an AB 310 Genetic Analyzer. We tested the accuracy, precision, sensitivity and reproducibility of the Auto2 multiplex with this instrument in our laboratory. We used 9947A control DNA samples of the AmpFℓSTR Identifiler™ kit to test the validation parameters together with non-probative DNA samples from whole blood and buccal swab samples of 29 healthy donors from different parts of Istanbul. Good results were obtained but interpretation of the peak patterns obtained on the AB 310 requires care and thorough optimization before they can be readily compard to those obtained from multiple capillary AB 31xx Analyzers. We succesfully optimized and validated the SNPforID Auto2 multiplex system for identification analyses in our laboratory.
