Rhabdomyosarcoma and neuroblastoma were stratified into known molecular subtypes: embryonal/fusion-negative (eRMS) and alveolar/fusion-positive rhabdomyosarcoma (aRMS), and neuroblastoma MYCN-non amplified (MYCN-NA), MYCN-amplified (MYCN-A), 11q wild type (11qWT), and 11q-deleted (11qLOH). The gene discussed is MYCN; the disease is rhabdomyosarcoma.
