MetaSystems Probes has already certified a large part of its portfolio, according to IVDR. For organizational reasons, we currently provide only the IVDD product.
Discover all IVDR-certified products
XL t(10;11) MLLT10/KMT2A DF consists of an orange-labeled probe hybridizing to the MLLT10 gene region at 10p12.3 and a green-labeled probe hybridizing 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.
Chromosomal rearrangements of the KMT2A (lysine methyltransferase 2A) gene, formerly MLL (mixed lineage leukemia), are associated with various hematological disorders. Most patients suffer from acute myeloid leukemia (AML) or acute lymphoblastic leukemia (ALL), while only a minority develops mixed lineage leukemia (MLL). Several chromosomal aberrations involving the KMT2A gene have been identified. However, the majority of leukemias result from translocations leading to KMT2A fusions. More than 90 KMT2A translocation partner genes fused to the 5´- KMT2A portion have been identified. The most common translocation partners in KMT2A associated leukemia are AFF1, MLLT3, MLLT1, MLLT10, ELL and AFDN, described here in the order of their frequency. MLLT10 (MLLT10 Histone Lysine Methyltransferase DOT1L Cofactor), previously known as AF10, is one of the most frequent fusion partners of KMT2A across all acute leukemia cases. KMT2A-MLLT10 fusions result from multiple breakpoints in both gene loci. The subsequent chromosomal rearrangements include reciprocal translocations, insertions, inversions, deletions and duplications. MLLT10 is a cofactor of the histone H3K79 methyltransferase DOT1L and mediates the interaction of AFF1, MLLT1 and MLLT3 with DOT1L. The consequence of the presence of KMT2A-AFF1, AFF1-KMT2A, KMT2A-MLLT3, KMT2A-MLLT1, and KMT2A-MLLT10 fusions is an increased and extended H3K79 methylation signature that is a requirement for the maintenance of RNA transcription. DOT1L inhibitors are promising candidates for clinical treatment which are currently being evaluated.
XL t(10;11) MLLT10/KMT2A DF hybridized to bone marrow cells, two aberrant cells are shown. An insertion of portions of the green signal into the orange signal has occured generating a pattern of 2 green, one orange and one green-orange colocalization/fusion signal.
Normal Cell:
Two green (2G) and two orange (2O) signals.
Aberrant Cell (typical results):
Two green (2G), one orange (1O), and one green-orange colocalization/fusion signal (1GO).
Aberrant Cell (typical results):
Two green (2G), two orange (2O), and one green-orange colocalization/fusion signal (1GO).
Certificate of Analysis (CoA)
or go to CoA DatabaseMetaSystems 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.
We hope you had a chance to meet us.
The IVDR is effective and our probes stay the same! A large segment of our portfolio is already IVDR-certified. Our priority is to give you a smooth transition into the IVDR era.
