APOL1 and hypertensive disorder: Elijovich et al. concluded that “substantial evidence from different racial and ethnic groups supports a genetic basis for the variation in the BP response to salt.”41 Aronow et al. noted: “Japanese appear to have a higher frequency of salt sensitivity than whites, possibly influenced by more prevalent polymorphisms of the angiotensinogen, alpha-adducting, and aldosterone synthase genes.”30 Whelton et al. described that “the excess risk of CKD outcomes in at least some blacks with hypertension may be due to the presence of high-risk APOL1 (apolipoprotein L1) genetic variants.”25
