Notably, we compared the presence of the specific cassette exons in RNA from normal brain and neuroblastoma (for ATP6v0A1, STRADA, PCNP and CS) and from skeletal muscle and rhabdomyosarcoma (for TPM3, TPD52L2, NAP1L1, METT10 D and SLC25A3). This evidence concerns the gene STRADA and rhabdomyosarcoma.
