All known KMT2A gene rearrangements are subclassified either into reciprocal (balanced) chromosomal translocations (n = 91), spliced fusions (n = 3 + 9), inversion on chromosome 11 (n = 6 + 1), deletions on chromosome 11 (n = 3) and TPG chromatin fragment insertions into the KMT2A gene, or vice versa, KMT2A gene fragment insertions into the TPG’s (n = 12). A few of the possible gene rearrangements are depicted at the bottom where different genetic scenarios are indicated. Since we had analyzed more than 400 complex KMT2A rearrangements, most of these scenarios have been identified, apart from chromotripsis which is a known mechanism to generate a multitude of gene fusions in solid cancer, but not in hemato-malignant tumors.
