Within the 3 cancer types (ovarian cancer, esophageal cancer and lung adenocarcinoma) that were commonly mutated in BRD9 and ACTL6A, a significant comutation relationship (p<0.001, log odds ratio = 1.051) was also shown in BRD9 and ACTL6A (Fig 7), which suggested that they may drive the oncogenic process together by affecting the same pathways. Here, BRD9 is linked to ovarian carcinoma.
