NCOA2 and rhabdomyosarcoma: The WHO classification scheme divides rhabdomyosarcoma RMS into four different subtypes: embryonal, alveolar, spindle cell/sclerotic, and pleomorphic subtypes (5) and mentions new subtypes to be studied more, such as rhabdomyosarcoma associated with the EWSR1/FUS::TFCP2 gene fusion and the MEIS1::NCOA2 gene fusion (5, 6).
