Yk. Keung et al., TRANSLOCATION(1-22) IN REFRACTORY-ANEMIA AND THE PROGNOSTIC-SIGNIFICANCE OF KARYOTYPIC ABNORMALITIES IN REFRACTORY-ANEMIA, Cancer genetics and cytogenetics, 106(1), 1998, pp. 72-75
The most common cytogenetic abnormalities associated with myelodysplas
tic syndromes are deletions of chromosomes 5 and 7 and trisomy 8. Reci
procal translocation is relatively uncommon in refractory anemia. We d
escribe a case of refractory anemia associated with trisomy 8 and a de
rivative chromosome 22 resulting from t(1;22)(q11;q11.2). The diseases
and the role of the various genes that are mapped to these breakpoint
s are discussed. The prognostic significance of karyotypic abnormaliti
es in refractory anemia are reviewed. (C) Elsevier Science Inc., 1998.
