The meeting of the German Society of Human Genetics (gfh) was held in Weimar, Germany this week and of course the attendees had the opportunity to visit the joined booth of MetaSystems and MetaSystems Probes. Main topics of the exhibition have been the latest advancements of the Neon case and imaging platform and RapidHyb, the revolutionary fast hybridization times of MetaSystems Probes' FISH probes.

A number of recurrent chromosomal abnormalities have been shown to have prognostic significance in acute lymphoblastic leukemia, 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 MDS and AML has also been observed, and transcriptional similarities between KMT2A amplified and KMT2A rearranged leukemias were identified.

Two green-orange (2GO) fusion signals representing the two normal KMT2A loci.
Aberrant Cell (typical results):
One green (1G), one orange (1O), and one green-orange (1GO) fusion signal, indicating a chromosome break in the KMT2A locus.
