We note that PIK3CA double mutations are relatively more dominant in BRCA, IDC (Breast Invasive Ductal Carcinoma), ILC (Breast Invasive Lobular Carcinoma), COAD, and UEC (Uterine Endometrioid Carcinoma) subtypes (Fig. 2b). The gene discussed is PIK3CA; the disease is endometrial endometrioid adenocarcinoma.
