Obesity and Leanness Caused by Mutations in the Leptin Gene: Already 6 Pathogenic Mutations Reported in this Gene

Abstract

Obesity and leanness are the medical conditions in which excess and deficient body fat present respectively. It may have an adverse effect on health, leading to reduced life expectancy and increased health problems. Environmental factors, especially increased consumption of high caloric diet, are considered responsible for the obesity epidemic, although genetic factors also contribute dysregulation of food consumption. Leptin gene may have an effect on the obesity and leanness because six pathogenic mutations already reported in leptin gene. Leptin gene mutations have a vital role to cause different types of cancers.
