Elliptocytosis in myelodysplastic syndrome associated with translocation (1;5)(p10;q10) and deletion of 20q

Acquired elliptocytosis is a red blood cell abnormality occasionally associ ated with myelodysplastic syndrome (MDS). A Japanese male with MDS who pres ented with elliptocytosis had mild anemia and hypercellular bone marrow wit h three lineage-dysplasia. He was diagnosed with refractory anemia of MDS. Cytogenetic analysis of bone marrow cells showed 47,XY, +1,der(1;5)(q10;p10 ),t(1;5) (p10;q10),del(20)(q11) in 70% of the analyzed cells. Analysis of r ed blood cell membrane proteins by sodium dodecyl sulphate-polyacrylamide g el electrophoresis showed normal electrophoretic patterns with no quantitat ive abnormalities of each protein. Del(20q) and/or t(1;5)(p10;q10) might be associated with elliptocytosis in this patient. (C) Elsevier Science Inc., 1998.
