Loss of chromosome 22 in patients with refractory anemia with excess of blasts (RAEB) in transformation and acute leukemia after RAEB

Cancer Genet Cytogenet. 1992 Jul 15;61(2):210-2. doi: 10.1016/0165-4608(92)90090-u.

Abstract

We report studies of 12 patients with refractory anemia and excess of blasts in transformation (RAEB-t) and 17 with acute myeloblastic leukemia (AML) after RAEB. Besides chromosome 5 and 7 abnormalities, five patients with complex karyotypic changes had monosomy 22. This association is discussed in relation to the hypothesis of a suppressor gene located on chromosome 22.
