Mutations in other SWI/SNF chromatin remodeling subunits are often detected simultaneously in the same tumor (Table 5), including ARID2, PHF10, SMARCC2, SMARCA2, SMARCC1, SMARCD3, SMARCE1, ARID1A, ARID1B, DPF1, and GLTSCR1, involving missense mutation, in frame del, splice region, nonsense mutation, frame shift del, frame shift ins, in frame ins and splice site, the former being more common. The gene discussed is SMARCD3; the disease is neoplasm.
