Background: Monogenic obesity is a rare form of obesity caused by pathogenic variants in genes implicated in the leptin–melanocortin receptor (MC4R) signaling pathway. The MC4R pathway plays a crucial role in the regulation of satiety, energy balance, and body weight. Abnormalities in the leptin–melanocortin pathway are characterized by early weight gain, hyperphagia, and severe obesity.Objective: To investig...
