PDGFRA/CHIC2/FIP1L1, PDGFRB, FGFR1
Idiopathic hypereosinophilic syndrome (HES), or primary eosinophilia, is a chronic and typically slowly progressive disease that eventually results in organ damage. Several molecular mechanisms have been identified, including FIP1L1-PDGFRα and rearrangements of PDGFRβ and FGFR1. The presence of any of these abnormalities is associated with positive response to imatinib mesylate (Gleevec) therapy. While molecularly defined eosinophilias are relatively rare, up to one-quarter of HES patients have been shown to harbor one of these mutations. In these patients, imatinib therapy improves 5-year survival rates to from ~75% to 90-95% and reduces rates of progression from 50% down to less than 1%.
