ARID1A plays a role in DNA double-strand brink (DSB) repair and the composition of Brahma-related gene 1/brahma (BRG1/ BRM)-associated factor (cBAF) complex and SWItch/Sucrose Non-Fermentable (SWI/SNF) complexes; therefore ARID1A mutation is considered as an early event of malignant tumor progression in OCCC [183]. Here, ARID1A is linked to cancer.
