Furthermore, MTHFD2 mutations in ovarian cancer samples were A > C (2.68%), A > G (4.46%), A > T (0.00%), C > A (13.39%), C > T (22.32), C > G (8.04), G > A (21.43%), G > C (7.14%), G > T (8.04), T > A (8.04%), T > C (5.36%), T > G (2.68%). The gene discussed is MTHFD2; the disease is ovarian cancer.
