In a logistic regression analysis with age, duration, BMI, HbA1c, systolic and diastolic blood pressure, sex, previous or current smoking and studied polymorphisms and HLA-DQB1 risk genotypes as independent variables, having the LTA T60N A allele in type 1 diabetic patients was associated with increased risk diabetic nephropathy (OR 2.55[1.11–5.86],p = 0.03), (Figure 1a). Here, HLA-DQB1 is linked to diabetic kidney disease.
