FGF21 and type 2 diabetes mellitus: We identified several associations with metabolic and anthropometric traits (all with statistical confidence < 6 × 10−5), most likely not detected before because of limited power: the FGF21 rs838133 A allele is associated with stronger effects on higher waist-hip ratio and higher blood pressure, despite an association with lower total body-fat percentage, than its effects on BMI, and has no detectable effect on type 2 diabetes.
