ZNF521 encodes a zinc-finger transcription factor that has roles in various biological processes involving stem cells, such as erythroid/myeloid/adipocyte/osteoblast differentiation, neural development, and bone formation, and is also implicated in diseases such as pancreatic, hepatic, gastric, bladder, breast, and ovarian cancers [131]. Here, ZNF521 is linked to ovarian cancer.
