“…DNA quality was assessed using a Nanodrop Spectrophotometer ND-2000 (Thermo Scientific, Wilmington, DE, USA) and by agarose gel electrophoresis assay to ensure genomic integrity. The genomic region was amplified using primers as previously described (Nhan et al, 2018) (Figure 1). Exclusion criteria for genotyped SNPs was deviation from Hardy-Weinberg equilibrium (HWE, P<0.05) in the controls.…”
