Abstrakt: The RAS/mitogen-activated protein kinase pathway plays a significant role in cell cycle regulation. Germline mutation of this pathway leads to overlapping genetic disorders, RASopathies, and is also an important component of tumorigenesis. Here we describe a rare case of myelodysplastic syndrome with monosomy 7 in a pediatric patient with a germline RRAS mutation. RRAS mutations have been implicated in the development of juvenile myelomonocytic leukemia, but our case suggests RRAS mutations display a broader malignant potential. Our case supports the recommendation that genetic testing should include RRAS in suspected RASopathy patients and if identified, these patients undergo surveillance for hematologic malignancy.
