Genetic Contributors to Obesity

Genetic forms of obesity contribute to ∼7% of severe obesity in children and adolescents. The exact global prevalence of monogenic and syndromic forms of obesity is not well established, most likely due to missed or delayed diagnosis. The challenge in determining the prevalence can be attributed to the lack of consensus on identifying and evaluating symptoms of genetic defects in a timely manner and hence a vastly undertested patient population. Further large-scale and long-term studies are needed to advance the understanding of this unique phenotype of obesity and effective treatment options."
