About Deletion 5q Chromosomal AbnormalityChromosomal (cytogenetic) abnormalities are detected in about half of patients with myelodysplastic syndrome (MDS), and involve one or more specific chromosomes. The most common cytogenetic abnormalities in MDS are deletions in the long arm of chromosomes 5, 7, and 20. Another common abnormality is an extra copy of chromosome 8. A deletion involving the 5q chromosome is the most frequent identified abnormality and may be involved in 20 percent to 30 percent of all MDS patients with cytogenetic abnormalities.
