XL del(20q) plus consists of an orange-labeled probe hybridizing to the PTPRT gene region at 20q12 and a green-labeled probe hybridizing to the MYBL2 gene region at 20q12-13.1.
Probe maps are created in accordance with the intended purpose of the product. Solid colored bars do not necessarily indicate that the probe fully covers the indicated genomic region. Therefore, caution is advised when interpreting results generated through off-label use. Probe map details based on UCSC Genome Browser GRCh37/hg19. Map components not to scale. Further information is available on request.
Myelodysplastic syndromes (MDS) are a group of hematopoietic stem cell disorders associated with ineffective hematopoiesis and peripheral blood cytopenias. MDS patients have a significant risk of progression to acute myeloid leukemia. In about 50% of de novo MDS, cytogentic aberrations are observed; deletions are predominant, translocations are rare. Recurrent abnormalities are del(5q), monsomy 7, del(7q), del(20q), del(17p) and del(11q).
Del(20q) is a recurrent but rare aberration and is present in about 3-7% of MDS patients. The majority of cases have an interstitial deletion which is flanked by the PTPRT gene and includes the MYBL2 gene. Sole del(20q) is associated with a more favorable outcome.
Normal Cell:
Two green (2G) and two orange (2O) signals.
Aberrant Cell (typical results):
Two green (2G) and one orange (1O) signal resulting from loss of one orange signal.
Aberrant Cell (typical results):
One green (1G) and two orange (2O) signals resulting from loss of one green signal.
Aberrant Cell (typical results):
One green (1G) and one orange (1O) signal resulting from loss of one green and one orange signal.
