Clinical Info

Systemic mastocytosis is characterized by the infilitration of clonal mast cells in the bone marrow, tissue, liver, and skin. Mutational testing for KIT D816V is a diagnostic tool for systemic mastocytosis because the majority of confirmed diagnoses harbor this mutation. Bone marrow evaluation is the primary diagnostic tool for systemic mastocytosis and provides the most reliable prognosis. Patients that harbor the KIT mutation exhibit resistance to tyrosine kinase inhibitor therapy, such as imatinib. When KIT is mutated in the presence of RUNX1 the patient prognosis is unfavorable.
