%X The authors describe a 5-year-old girl who developed a Noonan syndrome-like disorder as a result of the CBL c.1194C>G/p.His398Gln variant, including headache, papilledema, intracranial hypertension, hyperproteinorrhachia, leucorrhachia, and brain inflammation and vasculitis with CD3 positive lymphocyte infiltration. The patient responded partially to corticosteroids, acetazolamide, and ventriculoperitoneal valve placement. The serum cytokine profile revealed persistently elevated levels of IL-1 RA, IL-2R alpha, IL-6, IL-18, MCP-1, and MCP-3. Cyclophosphamide was used as a bridge to allogeneic hematopoietic stem cell transplantation in this case.
