In contrast to SMARCA2/4 and ARID1A/1B/2 genes, BCL7A seems to be specifically mutated in lymphomas that are either derived from or phenotypically similar to germinal center B cells, such as germinal center B cell-like (GCB) DLBCL [86], FL [121], Burkitt lymphoma (BL) [122], and MM [123]. Here, BCL7A is linked to Miyoshi myopathy.
