title: Chromosomal marker 20q- in cases of osteomyelosclerosis and CML.
abstract: Two male patients with myeloproliferative disorders (osteomyelosclerosis in one and CML in the other) were found to have a chromosomal marker 20q- in blood cells (unstimulated short time cultures). Marked erythropoietic disturbances were not revealed in these cases. The specificity of the 20q- marker for red cell disorders is discussed.
