About Myelodysplastic Syndromes
Myelodysplastic syndromes (MDS) are a group of hematologic malignancies
that affect approximately 300,000 people worldwide. MDS patients must often
rely on blood transfusions to manage symptoms of anemia and fatigue until they
develop life-threatening iron overload and/or toxicity, thus underscoring the
critical need for new therapies targeting the cause of the condition rather
than simply managing its symptoms .

About 5q Deletion Chromosomal Abnormality
Chromosomal (cytogenetic) abnormalities are detected in more than half of
patients with myelodysplastic syndrome (MDS), and involve a deletion in all or
part of one or more specific chromosomes.
(Photo: http://www.
The disorder , called supernumerary der(22) t(11;22) or Emanuel syndrome,
results from the havoc caused by an extra chromosome composed of parts of
chromosome 11 and chromosome 22. "The
hairpins and cruciforms are weak points where the DNA can break and rearrange
with DNA from other chromosomes. Unlike
more random, rarer chromosome translocations, the rearrangement between
chromosomes 11 and 22 tends to recur, which led the researchers to investigate
their DNA breakpoints in detail.
