In recent years, immunophenotype and cytochemistry analysis are found valuable in the diagnosis of AML, and immunophenotyping surface type molecules like CD123, CD45, CD34, CD38 have been reported to help confirm the diagnosis of AML (Prada-Arismendy, Arroyave & Röthlisberger, 2017). The gene discussed is CD34; the disease is acute myeloid leukemia.
