Hypertension and diabetes mellitus are important risk factors for chronic kidney disease (CKD). We previously showed that the C -> T polymorphism (rs6929846) of BTN2A1 was significantly associated with myocardial infarction. The purpose of the present study was to examine an association of rs6929846 of BTN2A1 with CKD in individuals with or without hypertension or diabetes mellitus, thereby contributing to the personalized prevention of CKD in such individuals separately. The study population comprised 7,542 unrelated individuals, including 2,289 subjects with CKD [estimated glomerular filtration rate (eGFR) <60 ml/min/1.73 m(2)] and 5,253 controls (eGFR >= 60 ml/min/1.73 m(2)) with or without hypertension or diabetes mellitus. The Chi-square test, a multivariable logistic regression analysis with adjustment for covariates, as well as a stepwise forward selection procedure revealed that the C -> T polymorphism (rs6929846) of BTN2A1 was significantly associated with CKD in normotensive individuals, in diabetic individuals and in individuals with hypertension and diabetes mellitus, or without either condition, with the T allele representing a risk factor for CKD. Stratification of subjects based on hypertension or diabetes mellitus may thus be important in order to achieve personalized prevention of CKD with the use of genetic information.
