Infants between 1–3 months had a 5.5-fold increased risk of anemia (p < 0.001, χ2 = 27.07, OR = 5.5, 95%CI: 2.7–11.2) and a 1.5-fold increased risk of liver cytolysis with increased ALT values (p = 0.019, χ2 = 5.50, OR = 1.5, 95%CI: 1.1–2.2). The gene discussed is GPT; the disease is anemia (phenotype).
