Hierarchical clustering of the CESH profiles of the 10 t(11;18)(q21;q21)-positive MALT lymphomas by comparing them to their t(11;18)(q21;q21)-negative counterparts. Genomic regions that are underexpressed are marked in red whereas those that are overexpressed are marked in green. LL31, LL53, LL57 and LL87 are MALT lymphomas in which exon 7 of API2 is fused to exon 5 of MALT1; LL29, LL27, LL51 and LL79 are MALT lymphomas in which exon 7 of API2 is fused to exon 8 of MALT1; LL39 and LL72 are MALT lymphomas in which exon 7 of API2 is fused to exon 9 of MALT1. Group A is composed of samples LL31, LL53, LL57, LL87, LL29 and LL51; group B contains samples LL39, LL72, LL27 and LL79.
