Fluorescence in situ Hybridization (FISH)
Clinical Significance:
Myelodysplastic syndromes (MDS) are a heterogeneous group of clonal hematopoietic disorders, characterized by ineffective maturation of the myeloid cells of the bone marrow. Among MDS patients, 45-40% have at least one chromosome rearrangement, the most common of which can be detected using this fluorescence in situ hybridization (FISH) panel (-5/5q-, -7/7q-, +8, 20q-).
This panel of FISH probes can increase the detection rate of chromosome abnormalities at diagnosis and aid in follow-up testing for clinically significant chromosome abnormalities in MDS.
The identification of the specific chromosome regions involved in a patient's disease may play a significant role in treatment decisions as MDS targeted therapies are developed.
Documentation:
Four probe sets associated with myelodysplastic syndrome (MDS) are included in this panel: -5/5q-, -7/7q-, +8, 20q-. 100-300 interphase nuclei are scored for each probe set to detect gain, loss, or rearrangements of the probe regions
