Seven Novel Deleterious LEPR Mutations Found in Early-Onset Obesity: a ΔExon6–8 Shared by Subjects From Reunion Island, France, Suggests a Founder Effect

Among seven newly discovered LEPR mutations in this French obese population, we identified a LEPR frameshift mutation shared by six subjects from Reunion Island. This observation suggests a founder effect in this Indian Ocean island with high prevalence of obesity and supports a recommendation for systematic screening for this mutation in morbidly obese subjects in this population.
