Genetic landscape of mucosal-associated lymphoid tissue (MALT) lymphomas. (A) Frequency of genetic events occurring in at least 5% of cases. Although PRDM1 appeared among the most frequently inactivated genes, most of the deletions also comprised TNFAIP3, making it difficult to ascertain the exact role of this lesion in MALT lymphomas. (B) Heatmap of the genetic landscape of MALT lymphomas. (C) Heatmap of pathways most commonly affected by genetic events in MALT lymphomas. (B and C) Each column represents one case. Red: present; White: absent; Gray: not available.
