    This variant results in increased agonist-promoted desensitization and has been well studied for impact on cardiovascular disease and drug response.
  • [Death]
    [atenolol; verapamil]
    The haplotype defined by the A allele of this SNP and the C allele of rs1801253 is associated with increased mortality risk in hypertensive patients with documented coronary artery disease. This increased risk was observed in patients with one or two copies of the AC haplotype. Significant association of the AC haplotype with mortality risk manifested in patients who were treated with the Ca++ channel blocker verapamil, but not in patients treated with the beta-blocker atenolol. Thus, individuals with the AC haplotype may experience better outcomes from treatment with atenolol vs. treatment with verapamil. No association was observed for nonfatal myocardial infarction or nonfatal stroke.
  • [Hypertension]
    Data from a study on forty hypertensive men and women aged 35 to 65 years suggest that this SNP together with rs1801253 in the ADRB1 gene are important determinants of antihypertensive response to metoprolol.
