SLCO1B1 and hypertensive disorder: We find no convincing evidence of an association between variants in SLCO1B1 with HTN or BP in the two GWAS that we tested [10, 11].This lack of association is not due to lack of power: the ICBP GWAS is sufficiently powered to detect effects as those expected (0.4 mm Hg per allele) yet we failed to see a significant association with the hexadecanedioate associated SNPs in Caucasians.
