Hum Mol Genet. 2012;21:3283–92. Four observational and one quasi-experimental studies including European adults were conducted to explore of CYP1A2 variants and CYP1A2 enzyme activity on blood pressure, focusing on caffeine as the potential mediator of CYP1A2 effects. CYP1A2 variants were associated with hypertension in non-smokers, but not in smokers. Higher CYP1A2 activity was linearly associated with lower blood pressure after quitting smoking. In non-smokers, the CYP1A2 variants were associated with higher reported caffeine intake, which in turn was associated with lower odds of hypertension and lower blood pressure. These observational and quasi-experimental results strongly support a causal role of CYP1A2 in BP control via caffeine intake.
