Juvenile myelomonocytic leukemia (JMML) is a rare form of chronic leukemia (cancer of the blood) that affects children, commonly those aged four and younger.[2] The name JMML now encompasses all diagnoses formerly referred to as juvenile chronic myeloid leukemia (JCML), chronic myelomonocytic leukemia of infancy, and infantile monosomy 7 syndrome. The average age of patients at diagnosis is two (2) years old.[2] The World Health Organization has included JMML as a subcategory of myelodysplastic and myeloproliferative disorders.
