Multivariable logistic regression analysis with adjustment for covariates revealed that the C→T polymorphism (rs6929846) of BTN2A1 was significantly associated with the prevalence of CKD in subject panels A (P = 0.0422; recessive model; odds ratio, 2.36) and B (P = 0.0386; dominant model; odds ratio, 1.21) with the T allele representing a risk for this condition.
Multivariable logistic regression analysis with adjustment for covariates revealed that rs6929846 of BTN2A1 was significantly associated with hypertension in subject panel A (P = 2.6 × 10(-6); odds ratio, 1.69) and in subject panel B (P = 0.0284; odds ratio, 1.24), with the T allele representing a risk factor for hypertension.
Multivariable logistic regression analyses with adjustment for covariates revealed that rs6929846 of BTN2A1 was significantly associated with MI in individuals with (P=0.0001; odds ratio, 1.49) or without (P=1.6x10-7; odds ratio, 2.32) hypertension</span>; in individuals with (P=0.0002; odds ratio, 1.65) or without (P=8.1x10-7; odds ratio, 1.76) DM; and in individuals without CKD (P=6.0x10-11; odds ratio, 2.03), but not in those with CKD.
A multivariable logistic regression analysis adjusted for age, gender, body mass index, smoking status and the prevalence of diabetes mellitus revealed that rs6929846 of BTN2A1 was significantly (dominant model; P=2.4x10-4; odds ratio, 1.29) associated with dyslipidemia, with the minor T allele representing a risk for this condition.
Multivariable logistic regression analysis of combined genotypes with adjustment for age, gender and diabetes mellitus revealed that rs662799 and rs6929846 significantly and synergistically affected dyslipidemia.
We previously showed that the -1131T→C polymorphism (rs662799) of the apolipoprotein A-V gene (APOA5) and the C→T polymorphism (rs6929846) of the butyrophilin, subfamily 2, member A1 gene (BTN2A1) were significantly associated with an increased serum concentration of triglycerides, a decreased serum concentration of high density lipoprotein (HDL)-cholesterol, and the prevalence of metabolic syndrome (MetS) in Japanese individuals.
Comparison of genotype distributions using the χ(2) test revealed that the genotype distributions and allele frequencies of rs6929846 were significantly (p<0.05) associated with MetS in Japanese subject panels A (T allele frequency: MetS, 0.091; controls, 0.054; p=6.1×10(-5)) and B (T allele frequency: MetS, 0.091; controls, 0.039; p=0013) but not in the Korean population samples (T allele frequency: MetS, 0.102; controls, 0.125; p=0.0997).
Longitudinal analysis with a generalized estimating equation and with adjustment for covariates revealed that rs6929846 of butyrophilin, subfamily 2, member A1 gene (BTN2A1) was significantly associated with the prevalence of hypertriglyceridemia (P=0.0001), hyper-LDL cholesterolemia (P=0.0004), and CKD (P=0.0007); rs2569512 of interleukin enhancer binding factor 3 (ILF3) was associated with hyper-LDL cholesterolemia (P=0.0029); and rs2074379 (P=0.0019) and rs2074388 (P=0.0029) of alpha-kinase 1 (ALPK1) were associated with CKD.

Multivariable logistic regression analysis with adjustment for age, sex, body mass index and smoking status revealed that rs6929846 was significantly associated with Type 2 diabetes (P = 0.0006; odds ratio 1.25) in all individuals, with the T allele representing a risk factor for this condition.
Given that diabetes mellitus is an important risk factor for myocardial infarction, the association of rs6929846 of BTN2A1 with myocardial infarction might be attributable, at least in part, to its effect on susceptibility to diabetes.
