ADRB2 and hypertensive disorder: In recentyears, several genetic polymorphisms have been identified in ADRB2,including rs1042713 G > A and rs1042714 C > G, and various studies haveconcentrated on the associations between these genetic polymorphisms and cardiovasculardiseases (Li et al., 2013; Zak et al., 2008).ADRB2 polymorphisms are relevant to several types of cardiovasculardiseases, such as hypertension, heart failure, MI and CAD (Brodde, 2008; Kulminski etal., 2010; Lou etal., 2010).
