IVDR Certification
This probe is IVDR-certified in compliance with the Regulation (EU) 2017/746 on in vitro diagnostic medical devices (IVDR).
MetaSystems Probes has already certified a large part of its portfolio, according to IVDR. For organizational reasons, we currently provide only the IVDD product.
XL MLL plus consists of an orange-labeled probe hybridizing proximal to the KMT2A gene region at 11q23.3 and a green-labeled probe hybridizing distal to the KMT2A gene region at 11q23.3.
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.
A number of recurrent chromosomal abnormalities have been shown to have prognostic significance in acute lymphoblastic leukemia (ALL), especially in B-precursor ALL. Some chromosomal abnormalities, such as high hyperdiploidy and the TEL-AML1 fusion, are associated with more favorable outcomes, while others, including the t(9;22), rearrangements of the KMT2A gene (chromosome 11q23), and intrachromosomal amplification of the AML1 gene (iAMP21), are associated with a poorer prognosis.
Chromosomal rearrangements involving the human KMT2A gene are recurrently associated with the disease phenotype of acute leukemias. The identification of KMT2A gene rearrangements is necessary for rapid clinical decisions resulting in specific therapy regimens. Amplification of KMT2A in myelodysplastic syndrome and acute myeloid leukemia has also been observed, and transcriptional similarities between KMT2A amplified and KMT2A rearranged leukemias were identified.
Clinical Applications
- Acute Lymphoblastic Leukemia (ALL)
- Acute Myelogenous Leukemia (AML)
XL MLL plus hybridized to bone marrow cells. Two aberrant interphase nuclei with one fusion signal and one separate orange and green signal each are shown, representing a translocation with KTM2A involvement.
Normal Cell:
Two green-orange colocalization/fusion signals (2GO).
Aberrant Cell (typical results):
One green-orange colocalization/fusion signal (1GO), one separate green (1G) and orange (1O) signal each resulting from a chromosome break in the respective locus.

Neon, the outstanding MetaSystems case and image management system, offers many tools and helpful gadgets to streamline routine workflows, for example in cytogenetics labs. The second MetaSystems User Day, addressed to MetaSystems clients from Germany, Austria, and Switzerland, provided in different workshops knowledge helping to unleash the full power of the system.
OOO MetaSystems Russia on the International Scientific Congress 'Genetics of XXI Century'
The Congress 'Genetics of XXI Century' in Moscow, Russia (May 2019) has been one of the most important events for the professional international community of geneticists. Our partner company in Russia OOO MetaSystems considered it a good occasion to present the new camera CoolCube 4 connected to a state-of-the-art Neon system to the public.
