The samples were matched for age, sex and diabetes status; all individuals had a serum creatinine level < 250 μmol/L
*For individuals without diabetes mellitus, controls were individuals with no HNF1B gene mutation or deletion detected on genetic testing; for individuals with diabetes mellitus, controls were individuals from the UNITED (Using pharmacogeNetics to Improve Treatment in Early-onset Diabetes) study with presumed type 1 diabetes
