In addition, the association between the C allele of the APOA5 polymorphism and MS was stable in both males (OR = 1.285, 95% CI = [1.050–1.574], P = 0.015) and females (OR = 1.339, 95% CI = [1.138–1.576], P = 4.52E − 04) after adjustment for age. The gene discussed is APOA5; the disease is myeloid sarcoma.
