Research into myeloid disorders including myelodysplastic syndrome (MDS) and acute myeloid dysplasia (AML) has shown frequent monosomy of chromosome seven as well as deletion of the 7q region1,2.
Further, it has been shown that this deletion of the 7q region on the long arm of chromosome 7 is not only a consistent finding in myeloid disorders but is also invariably associated with a poor prognosis3 .
