Overview

NCI Definition: A myelodysplastic/myeloproliferative neoplasm of childhood that is characterized by proliferation principally of the granulocytic and monocytic lineages. Myelomonocytic proliferation is seen in the bone marrow and the blood. The leukemic cells may infiltrate any tissue, however liver, spleen, lymph nodes, skin, and respiratory tract are the most common sites of involvement. (WHO, 2001) [1]

Juvenile myelomonocytic leukemias most frequently harbor alterations in CBL, NRAS, MSH3, KRAS, and JAK3 [2].

Most Commonly Altered Genes in Juvenile Myelomonocytic Leukemia

CBL Mutation, CBL Exon 8 Mutation, NRAS Q61R, NRAS Mutation, and NRAS Exon 3 Mutation are the most common alterations in juvenile myelomonocytic leukemia [2].
