NIH Websites Are Changing
Per Executive Order 14434, federal agencies are now using "Super Intelligence" (SI) in place of "Artificial Intelligence" (AI). You may see both terms across NIH content during this transition.

AML-MRC

A type of acute myeloid leukemia in which at least 20% of a patient’s blood or bone marrow is myeloblasts (immature white blood cells) and the patient has one of the following conditions: 1) has had myelodysplastic syndrome (MDS) or a myelodysplastic/myeloproliferative neoplasm (MDS/MPN) before, 2) cells that have changes in certain chromosomes that are similar to those found in MDS, or 3) at least 50% of the cells (of at least two types of blood cells) are abnormal. AML-MRC usually occurs in older adults and has a poor prognosis. Also called acute myeloid leukemia with myelodysplasia-related changes.
