ADRB1 and heart failure: Here, they showed that ADBR2 rs1042714 (c.79G>T, p.Glu27Gln) and ADRB1 rs1801253 (c.1165G>C, p.Gly389Arg) SNPs influenced survival in heart failure patients taking a high beta-blocker dose, highlighting how pharmacogenetic markers may have a potential use in the creation of dosing algorithms in clinical practice.
