CD34 and acute myeloid leukemia: BAALC, which maps on chromosome 8 at 8q22.3, is involved in neuroectodermal and hematopoietic development.8 The expression ofBAALC was reported as a precursor for hematopoiesis like the cluster of differentiation CD34+ in early hematopoietic cells.9 High expression of that was found in bone marrow of AML patients with a normal karyotype10 and identified as anindependent poor prognostic indicator, associated with shorter survival.11
