For example ARID1A, which only assembles with the canonical BRG1/BRM‐associated factor (BAF), has been often implicated in Wnt‐driven cancers (Heckl et al., 2018; Mathur et al., 2017; Mouradov et al., 2014; Renko et al., 2019), and several other canonical BAF components are simultaneously assembling on classical WRE (van Tienen et al., 2017). This evidence concerns the gene BANF1 and cancer.
