CABIN1 alterations and expression. A, Oncoprint showing alterations occurring across genes in the NFAT signaling pathway. Columns correspond to patients while genes are listed in rows. B, Lollipop plot showing the somatic nonsilent mutations found in CABIN1 gene with annotations of the amino acid changes. C, Heat map of CN status for cytoband 22q11 including the CABIN1 locus (annotated). Across this cytoband, segment colors vary from blue for strong CN losses to red for strong CN gains. Each row represents a sample, and each column represents a reported CN segment. Sample mutation status is noted to the right. D, Immunofluorescence expression analysis of CABIN1 (red), CD20 (green, top), and CD3 (green, bottom) in normal lymph node. Magnification: top and bottom left, 4×; top and bottom right, 40×. E, IHC analysis of CABIN1 expression in different MALT lymphomas (magnification all 20×). Top left, OAMZL with WT CABIN1; top right, OAMZL with CABIN1 CN losses; bottom left, parotid MZL; bottom right, lung MZL. White bars, 50 μm.
