We observed that mutations were frequent in malignant lymphoma (Germinal center B-cell derived lymphomas) for the BAF ATPase SMARCA2 (18%) and auxiliary subunits ARID1A (18%), ARIDB (32%), ARID2 (18%), and DPF3 (23%), and other subunits were also mutated at lower frequencies (Table 3). The gene discussed is SMARCA2; the disease is lymphoma.
