NCIt definition : A fusion gene that results from an Xp22.1-Xp21.3 microdeletion which causes a tail-to-tail
fusion of the IL1RAPL1 gene and the DMD gene. This rearrangement is associated with
Becker muscular dystrophy.;
NCIt note : The 1.8-megabase deletion removes the last exon of the dystrophin gene, the entire
GK and NR0B1 genes, and the MAGE-B gene cluster, but also three exons encoding the
intracellular signaling domain of interleukin-1 receptor accessory protein-like 1.
Therefore, the fusion gene product is a truncated form of the interleukin-1 receptor
accessory protein-like 1.;
