G6PD and dengue disease: When comparing hemoglobin levels between individuals without mutations and those with specific G6PD variants, statistically significant differences were observed during the dengue critical phase for two G6PD variants: a combination of c.1311C > T and c.1365-13T > C and the compound mutation of G6PD Viangchan (p = 0.02 and 0.01, respectively).
