Of these genes, several may be important for rhabdomyosarcoma, including a homeobox transcription factor (PROX1), a tumor suppressor (CD82), a transposable element (PDBD5), a muscle sodium channel (SCN4A), and a long intergenic non-coding RNA (LINC00689) (see Discussion). The gene discussed is PROX1; the disease is rhabdomyosarcoma.
