However, in our study, among the patients who consumed alcohol, the number of carriers of the MTHFR 677T allele and the risk of AAA was higher (OR = 2.46; 95% CI, 1.10–5.50; p = 0.03) than among the participants who did not drink (OR = 0.61; 95% CI, 0.33–1.14; p = 0.12). The gene discussed is MTHFR; the disease is triple-A syndrome.
