The association of WNK4 C6749T polymorphism with hypertension was found to be significant in allele contrast (OR = 2.04, 95% CI/: 1.60–2.59, P<0.01), dominant genetic model (OR = 2.04, 95% CI: 1.59–2.62, P<0.01) and homozygous genetic model (OR = 5.01, 95% CI: 1.29–19.54, P = 0.02) (Figure 4). Here, WNK4 is linked to Hypertension.
