Langerhans Cell Histiocytosis With <i>MAP2K1^E102_I103del</i> Mutation Successfully Treated With Trametinib. [PDF]

EJHaem
ABSTRACT The discovery of the MAPK pathway mutations in lesions of patients with Langerhans cell histiocytosis (LCH) has made targeted therapy an important therapeutic approach for these patients. Theoretically, the RAF‐independent mutation MAP2K1E102_I103del is naturally resistant to allosteric MEK inhibitors.
