FISH, Myeloid Neoplasms, MECOM (EVI1), 3q26.2
Test Summary
Disruption of the human entropic virus integration site (EVI1 or MECOM) gene located at chromosome band 3q26.2 is associated with myeloid neoplasms and is indicative of a poor prognosis. EVI1 rearrangements are especially frequent in myeloid blast crisis that evolves through tyrosine kinase inhibitors. It has been associated with dysplasia of megakaryocytes and alters differentiation of other myeloid cells. Associated rearrangements include inv(3)(q21q26), t(3;3)q21;q26), t(3;21)(q26;q22) and t(3;12)(q26;p13).
