A total of 12 significant SNPs associated with BMI were identified, of which 7 SNPs were also significantly associated with obesity, including rs1337406 (WLS), rs673612 (NTNG1), rs4449107 (FAM84A), rs9820485 (STAG1), rs73247924 (CCKAR), rs2083069 (ACADSB), and rs4942190 (DNAJC15). Here, STAG1 is linked to obesity due to melanocortin 4 receptor deficiency.
