We describe a patient with MPAL with a NUP98 (nucleoporin 98)‐NSD1 gene fusion (nuclear receptor binding SET domain protein1) and NRAS (neuroblastoma RAS viral oncogene homolog mutation) p.Gly61Arg mutation who was treated with upfront AML‐based chemotherapy, received hematopoietic stem cell transplant (HSCT), but unfortunately died from relapsed disease. The gene discussed is NRAS; the disease is mixed phenotype acute leukemia.
