Abstract excerpt
AIMS: To investigate the association of the Gly389 allele with positive head-up tilt test (HUT) in a Mexican Mestizo population. METHODS AND RESULTS: HUT results were compared between carriers (one or two copies of the Gly389 allele) and non-carriers (Arg389Arg genotype) of the Gly389 allele of the beta(1)AR gene in 50 patients with unexplained syncope. Thirty-three patients (66%) had a positive HUT. Patients...
