Until further notice, we will continue to provide IVDD products in various countries.
As part of our phased rollout, the IVDR-certified probes are now available in Austria, Belgium, Croatia, Cyprus, Estonia, France, Germany, Iceland, Italy, Liechtenstein, Luxembourg, Malta, Netherlands, Slovenia, and Switzerland, with the list of countries continuously expanding.
The XL 4q12 probe is a qualitative, non-automated test for the detection of deletions of the CHIC2 gene region at 4q12 and breaks in PDGFRA at 4q12 by fluorescence in situ hybridization (FISH). The product is intended as a diagnostic aid and assists in disease monitoring. The test population consists of patients with confirmed or suspected chronic myelomonocytic leukemia (CMML), myelodysplastic/myeloproliferative neoplasms (MDS/MPN) and myeloid/lymphoid neoplasms with eosinophilia and tyrosine kinase gene fusions (MLN-TK). Hybridization is to be performed on methanol/acetic-acid fixed cells derived from bone marrow or peripheral blood.
The XL 4q12 probe consists of a green-labeled probe hybridizing proximal to the FIP1L1 gene region at 4q12, an orange-labeled probe hybridizing to the CHIC2 gene region at 4q12 and an aqua-labeled probe hybridizing to the PDGFRA gene region at 4q12.
Probe maps for selected products have been updated. These updates ensure a consistent presentation of all gaps larger than 10 kb including adjustments to markers, genes, and related elements. This update does not affect the device characteristics or product composition. Please refer to the list to find out which products now include updated probe maps.
Probe map details are based on UCSC Genome Browser GRCh37/hg19, with map components not to scale.
XL 4q12 hybridized to lymphocytes. Two normal interphases are shown with two blue-green-orange fusion signals each.
Normal Cell:
Two green-orange-blue colocalization/fusion signals
(2BGO).
Aberrant Cell (typical results):
One blue-green-orange colocalization/fusion signal (1BGO) and one blue-green colocalization/fusion (1BG) resulting from loss of one orange signal.
Aberrant Cell (typical results):
One green-orange-blue colocalization/fusion signal (1BGO), one green-orange colocalization/fusion (1GO) and one separate blue (1B) signal resulting
from a chromosome break in the respective locus.
