The atherogenic index expressed as a continuous variable correlated independently with CASR rs7652589 in dominant model of inheritance (β = 0.10 ± 0.05, P = 0.021) together with BMI (β = 0.26 ± 0.05, P = 1.1E-8) and diabetic nephropathy (β = 0.09 ± 0.05, P = 0.044). Here, CASR is linked to diabetic kidney disease.
