AGTR1 polymorphism and cardiomyopathy were not significantly associated under allelic model A vs C (OR = 0.69, 95CI% = 0.46–1.03) and recessive model AA vs CA+CC (OR = 0.89, 95CI% = 0.34–2.30), but under the dominant model AA+CA vs CC (OR = 0.51, 95CI% = 0.38–0.68). The gene discussed is AGTR1; the disease is cardiomyopathy.
