NCIt definition : A myelodysplastic syndrome characterized by a deletion between bands q31 and 33 on
chromosome 5. The number of blasts in the bone marrow and blood is 5%. The bone marrow
is usually hypercellular or normocellular with increased number of often hypolobated
megakaryocytes. The peripheral blood shows macrocytic anemia. This syndrome occurs
predominantly but not exclusively in middle age to older women. The prognosis is good
and transformation to acute leukemia is rare. (WHO, 2001);
Alternative definition : NCI-GLOSS: A rare disorder caused by loss of part of the long arm (Q arm) of human
chromosome 5. This syndrome affects myeloid (bone marrow) cells, causing treatment-resistant
anemia, and myelodysplastic syndromes that may lead to acute myelogenous leukemia.;
