These variants were FTO (fat mass and obesity associated) (rs9939609), GNPDA2 (glucosamine-6-phosphate deaminase 2) (rs10938397), KCTD15 (potassium channel tetramerisation domain containing 15) (rs11084753), MC4R (melanocortin-4 receptor) (rs17782313), MTCH2 (mitochondrial carrier 2) (rs10838738), NEGR1 (neuronal growth regulator 1) (rs2815752), TMEM18 (transmembrane protein 18) (rs6548238), and SH2B1 (SH2B adaptor protein 1) rs7498665). This evidence concerns the gene KCTD15 and obesity due to melanocortin 4 receptor deficiency.
