The yearly MetaSystems Distributor Meeting (DM), brought into life in 2002 as a platform to gather all international partners of MetaSystems and other members of the global MetaSystems family, just ended last week. The DM is being organized in turns by MetaSystems Headquarters, MetaSystems USA (MGI), and MetaSystems Asia. Since MGI is celebrating its 25th anniversary in 2018 they decided to choose a special location: Nassau, The Bahamas!
XL 1p36/1q25 del

XL 1p36/1q25 del detects deletions in the short arm of chromosome 1. The orange labeled probe hybridizes to the CHD5 locus at 1p36. A green labeled probe hybridizes to the ABL2 locus at 1q25 and functions as a reference probe.
This probe is intended for methanol/acetic-acid fixed cells and tissue sections.
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 has also predictive character, the molecular status of 1p/19q is relevant for therapy decisions.
- Solid Tumors (Solid Tumors)
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.
