    Myelodysplastic syndromes (MDS) represent a clinically and genetically heterogeneous group of clonal haematopoietic diseases characterized by a short survival and high rate of transformation to acute myeloid leukaemia (AML). In spite of this variability, MDS is associated with typical recurrent non-random cytogenetic defects. Chromosomal abnormalities are detected in the malignant bone-marrow cells of approximately 40-80 % of patients with primary or secondary MDS. The most frequent chromosomal rearrangements involve chromosomes 5, 7 and 8. MDS often shows presence of unbalanced chromosomal changes, especially large deletions [del(5), del(7q), del(12p), del(18q), del(20q)] or losses of whole chromosomes (7 and Y). The most typical cytogenetic abnormality is a partial or complete deletion of 5q- that occurs in roughly 30 % of all MDS cases either as the sole abnormality or in combination with other aberrations as a part of frequently complex karyotypes. The mechanisms responsible for the formation of MDS-associated recurrent trans-locations and complex karyotypes are unknown.
