TaqMan SNP genotyping assays were performed in triplicate on serum cell-free DNA samples obtained from 26 Hmong individuals. Genotype calls (i.e., C/C, C/G, G/G) were made with TaqMan Genotyper Software (Applied Biosystems) and genotype frequencies were summarized according to A) the three possible genotypes: C/C, C/G, G/G, B) samples with (C/G, G/G) or without (C/C) the “G” allele. C) The genotypes of the entire cohort of samples (in triplicate) are visualized as an allelic discrimination plot.
