Melanocortin 4 Receptor Mutations in a Large Cohort of Severely Obese Adults: Prevalence, Functional Classification, Genotype-Phenotype Relationship, and Lack of Association with Binge Eating

Obese adult carriers of functionally relevant MC4R mutations do not specifically present with binge-eating disorder or a history of early-onset obesity. The onset and severity of the obesity in the carriers is related to the functional severity of the MC4R mutations.
