Obesity-related genes were retrieved in the Digsee database and the top 15 obesity-related genes were selected as disease genes (Adipoq, Igf1, Fto, Hsd11b1, Tnf, Gh1, Mc4r, Lep, Pparg, Il6, Crp, Lepr, Pomc, Lpl, and Ghr1). This evidence concerns the gene LEPR and obesity due to melanocortin 4 receptor deficiency.
