MC4R

MC4R makes a receptor involved in hunger, fullness, and energy use. Rare damaging changes inside MC4R can cause severe childhood obesity. The common rs17782313 marker is different: it sits far outside the gene, has only a small link to average body weight, and has no proven effect on appetite or food intake.
