Interestingly, we found that if more than or equal to two alleles A were present in the combination of donors’ CYP3A5*3 and recipients’ CYP3A4*1G genotype, there was a lower Tac C/D ration at week 1, 2, and 3 (P<0.001, P=0.001, and P<0.001), except at week 4 (P=0.082), and the probability of new-onset hypertension was lesser (P<0.001). Here, CYP3A4 is linked to Hypertension.
