In conclusion, people with the major allele of ATP2B1 rs17249754 are susceptible to hypertensionespecially in low intake of Ca and high ratio of Na and K.
The present study confirmed the significant association of ATP2B1 rs17249754 with risk of hypertension among Chinese children, but failed to replicate the association of CSK rs1378942, MTHFR rs1801133, CYP17A1 rs1004467, STK39 rs3754777 and FGF5 rs16998073 with BP/risk of hypertension.
Five gene variants, rs11066280 (C12orf51), rs12229654 and rs3782889 (MYL2), rs2072134 (OAS3), rs2093395 (TREML2), and rs17249754 (ATP2B1), were found to be associated with hypertension mostly in men (P = 4.76 × 10(-14) to 4.46 × 10(-7) in the joint analysis); three SNPs (rs11066280, rs12229654, and rs3782889) remained significant after Bonferroni correction in an independent population.
We also observed a significant association of 4 SNPs and the GRS with hypertension (ATP2B1 rs17249754: P = 0.02; CSK rs1378942: P = 0.02; CYP17A1 rs1004467: P = 0.02; MTHFR rs1801133: P = 0.03; GRS: P = 0.0004).
The major findings of this study were that four loci--rs10858911, rs2681472, rs17249754 and rs1401982--associated with any or all of four traits: hypertension (P = 0.001-4.6E-05; odds ratio, 0.83-0.87), systolic BP (P = 0.003-0.004), diastolic BP (P = 0.002-0.003) and cf-PWV (P = 0.002-0.004).
In contrast, in inactive group, two polymorphisms and genetic risk score were significantly associated with SBP (rs17249754: β = 1.26, 95% confidence interval (CI) 0.61-1.90, p < 0.001; rs1004467: β = 0.68, 95%CI 0.03-1.32, p = 0.039; genetic risk score: β = 1.54, 95%CI 0.74-2.33, p < 0.001); three polymorphisms and genetic risk score were significantly associated with hypertension (rs17249754: odds ratio (OR) = 1.27, 95%CI 1.08-1.49, p = 0.004; rs1378942: OR = 1.25, 95%CI 1.00-1.57, p = 0.050 (marginally significant); rs16998073: OR = 1.17, 95%CI 1.01-1.37, p = 0.044; genetic risk score: OR = 1.38, 95%CI 1.13-1.68, p = 0.001).
An additional hypertension case-control study confirmed that rs17249754 (in ATP2B1) increases hypertension risk in both the KARE and Health2 (meta-analysis, P-value=4.25 x 10(-9)) cohorts.
