Previous studies have shown that SETD1A played a key role in embryonic stem cell self‐renewal (Fang et al., 2016) and is required for breast cancer, lung adenocarcinoma, and colorectal cancer development (Fang et al., 2018; Jin et al., 2018; Salz et al., 2015; Salz et al., 2014). Here, SETD1A is linked to breast carcinoma.
