Obesity-associated noncoding sequences within FTO are functionally connected with IRX3, and long-range enhancers in this region recapitulate aspects of IRX3 expression, suggesting that the obesity-associated interval is part of IRX3 regulation; Irx3-deficient mice have lower body weight and are resistant to diet-induced obesity, suggesting IRX3 as a novel determinant of body mass and composition.
