BCL7A
BCL7A protein interacts with components of the SWI/SNF chromatin remodeling complex, implicating it in chromatin remodeling processes essential for normal cellular function.[@reichelFlowSortingExome2015a] Mutations in the BCL7A gene have been identified in diffuse large B-cell lymphoma (DLBCL) and other B-cell lymphomas, implicating this gene in the pathogenesis of these cancers. Importantly, BCL7A is one of a number of genes affected by aberrant somatic hypermutation in B-cell lymphomas, which complicates the interpretation of mutations at this locus. Due to the presence of some loss-of-function mutations, BCL7A has been described as a tumour-suppressor gene in DLBCL.[@balinas-gaviraFrequentMutationsAminoterminal2020b] The rate of DLBCLs with biallelic loss of this locus remains unclear.
