rs560887, p = 4 x 10(-7)) *654 normoglycemic subjects, replicated in 9,353 subjects *fasting plasma glucose (FPG) (beta = -0.06 mmol/l per A-allele, combined p = 4 x 10(-23)) and with pancreatic beta-cell function (Homa-B model, combined p = 3 x 10(-13)) in three populations; however it was not associated with type 2 diabetes risk. (ageing) Blood Glucose

T;T

Slightly lower blood glucose. Fasting Plasma Glucose is the amount of sugar in your blood when you wake up. It's required to power your body, but too much is very bad for you. Fasting plasma glucose between 5.6 mmol/L and 6.9 mmol/L (101 – 125 mg/dl) is considered pre-diabetes. Fasting plasma glucose higher than 7 mmol/L (126 mg/dl) is considered diabetes.

C;T

Slightly lower blood glucose. Fasting Plasma Glucose is the amount of sugar in your blood when you wake up. It's required to power your body, but too much is very bad for you. Fasting plasma glucose between 5.6 mmol/L and 6.9 mmol/L (101 – 125 mg/dl) is considered pre-diabetes. Fasting plasma glucose higher than 7 mmol/L (126 mg/dl) is considered diabetes.
