It has been reported that OVOL2 expression is negatively correlated with human breast cancer progression, and patients with breast cancer exhibiting high OVOL2 expression have longer relapse‐free survival (RFS) than patients with low OVOL2 expression.[15] However, a comparison of OVOL2 expression between breast cancer and normal breast tissues has not been performed. Here, OVOL2 is linked to breast carcinoma.
