XL FGFR1 consists of a green-labeled probe hybridizing proximal to the FGFR1 gene region at 8p11.2 and an orange-labeled probe hybridizing distal to the FGFR1 gene region at 8p11.2.
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.
In 2008, the World Health Organization (WHO) classification of tumors of hematopoietic and lymphoid tissues introduced a new category for myeloid and lymphoid neoplasms with eosinophilia and abnormalities of PDGFRA, PDGFRB or FGFR1. Many of these cases present as a myeloproliferative neoplasm, usually with eosinophilia.
The 8p11 myeloproliferative syndrome (MPD) also known as stem cell leukemia-lymphoma syndrome (SCLL) is associated with translocations disrupting FGFR1. Imatinib, which induces durable responses in MPDs with PDGFRA and PDGFRB fusion genes, is inactive in patients with FGFR1 translocations.
- Chronic Myelogenous Leukemia and Myeloproliferative Neoplasms (CML/MPN)
Two green-orange (2GO, may appear yellow 2Y) fusion signals.
Aberrant Cell (typical results):
One green-orange (1GO, may appear as yellow) fusion signal and one green (1G), one orange (1O) indicating a chromosome break in the FGFR1 locus.
