The translocation fuses the API2 gene to the MALT1 gene and generates a functional API2-MALT1 transcript.     ///    "Comparative sequence analysis between the API2-MALT1 fusion on der(11) and the MALT1-API2 fusion on der(18) showed extensive alterations including deletions, duplications and non-template-based insertions at the fusion junctions in all cases examined. "    ///    "An extensive sequence search failed to reveal any known sequence motifs that might be associated with chromosomal recombination or any novel consensus sequences at or near the breakpoints on both der(11) and der(18) except in one case, in which Alu repeats spanned the breakpoint of the MALT1-API2 fusion.
