SNPs were selected from association results of type 2 diabetes (11 SNPs), obesity (nine SNPs), BMI (three SNPs), waist circumference (one SNP), fasting glucose (seven SNPs), fasting insulin (eight SNPs), fasting HDL-cholesterol (two SNPs) and fasting triacylglycerol (one SNP). Here, INS is linked to obesity due to melanocortin 4 receptor deficiency.
