However, because BMI is a quantitative trait with obesity representing the right tail of the distribution, attempts to address this distinction are warranted.he brain derived neurotrophic factor (BDNF) is involved in weight regulation downstream of the MC4R. Mutations in single genes of the leptinergicâmelanocortinergic pathway have been shown to have a monogenic effect on the development of obesity.
