Many different methods have been established for SNP detection and especially minisequencing has often been used. For our study we have selected 5 Y-chromosomal SNPs (M9, M17, M45, M170, M173) based on the degree of polymorphism. PCR primers were designed with the aim to get amplicon lengths of < 200 bp. The Y-SNPs were optimized in singleplex reactions and combined to multiplex approaches by sequential optimization. Finally, we were able to analyse these 5 Y-chromosomal SNPs in one PCR/SNaPshot reaction. To validate this method for forensic stain analysis we investigated bones, bloodstains, cigarette butts and epithelial cells and mixed stain containing male-female DNA. Additionally, we typed 40 unrelated Caucasian individuals to obtain our regional haplotype frequencies.
