Product Description

XL 1p36/1q25 del

XL 1p36/1q25 del consists of an orange-labeled probe hybridizing to the CHD5 gene region at 1p36.3 and a green-labeled probe hybridizing to the ABL2 gene region at 1q25.2.

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.

Clinical Details

The 2016 ´World Health Organization Classification of Tumors of the Central Nervous System´ (WHO 2016) combines, for the first time, histological features and molecular signatures for the definition of many tumor entities. Gliomas are a category of tumors of the brain and spinal cord starting in glia cells. Oligodendrogliomas are a subtype of gliomas accounting for up to 18% of all cases. According to the WHO 2016, the classification of an oligodendroglioma requires information about the isocitrate dehydrogenase mutation status and 1p/19q loss of heterozygosity (LOH). LOH of 1p can be detected in about 67% of oligodendroglial tumors and has also been identified in neuroblastomas and other tumor entities. Co-deletion of 1p/19q is a well-accepted prognostic biomarker in neuro-oncology. Patients suffering from anaplastic oligodendroglioma harboring 1p/19q deletion generally have a good prognosis. Co-deletion of 1p/19q also has predictive character, the molecular status of 1p/19q is relevant for therapy decisions.

IVDR Certification

MetaSystems Probes has received IVDR certification for our initial 26 fluorescence in situ hybridization (FISH) probes from the notified body, BSI. Achieving this milestone was not without its challenges, and we are delighted to have accomplished IVDR certification for this probe set at an early stage.
