BRD9 is the bromodomain-containing subunit of the BAF (BRG-/BRM-associated factor)157 and its close homolog BRD7 is the subunit of PBAF (polybromo-associated BAF).158 BAF and PBAF are two variants of the SWI/SNF complex, which regulate gene expression, DNA replication and DNA repair.159 Overexpression of BRD9 is found in several cancers, including cervical cancer.160. This evidence concerns the gene BRD9 and cancer.
