FIP1L1-PDGFRA and c-kit D816V mutation-based clonality studies in systemic mast cell disease associated with eosinophilia

Abstract

Laboratory methods to detect both FIP1L1-PDGFRA and c-kit D816V mutations were combined with immunomagnetic cell separation to study the extent of clonal involvement by both myeloid and lymphoid cells in 3 patients with systemic mastocytosis associated with eosinophilia. The results suggested an early stem cell origin for the FIP1L1-PDGFRA mutation.
