(a) ERCC2, 751A/C, pre-WGA SNP genotyping represents the general allelic discriminating plots for DNA from blood (left) and from matched, non-amplified nail clippings (right). Samples from blood generally clustered more tightly. Allele X (red): homozygous wild-type (AA); Allele Y (blue): homozygous variant (CC); Both (green): heterozygous (AC); NTC (black): Non-Template Control. (b) ERCC2, 751A/C, post-WGA SNP genotyping represents the general allelic discriminating plots for nail-extracted DNA samples amplified by MDA (left) and Omniplex (right). Amplified nail-extracted DNA samples generally scattered more on the graphs compared to non-amplified samples. Left: post-MDA with one undetermined (x) and one inconsistency (#2). Right: post-OmniPlex. Allele X (red): homozygous wild-type (AA); Allele Y (blue): homozygous variant (CC); Both (green): heterozygous (AC); NTC (black): Non-Template Control.
