XL RUNX1 consists of an orange-labeled probe hybridizing proximal to the RUNX1 gene region at 21q22.1 and a green-labeled probe hybridizing distal to the RUNX1 gene region at 21q22.1.
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.
Several recurrent balanced translocations and inversions, and their variants, are recognized in the WHO category acute myeloid leukemia (AML) with recurrent genetic abnormalities. Furthermore, several cytogenetic abnormalities are considered sufficient to establish the WHO diagnosis of AML with myelodysplasia-related features if 20% or more blood or marrow blasts are present.
The RUNX1 gene, located on chromosome 21q22.1, is crucial for the establishment of definite hematopoiesis and the generation of hematopoietic stem cells in the embryo. The most common translocations involving RUNX1 are the t(8;21) RUNX1T1/RUNX1 in AML and t(12;21) ETV6/RUNX1 in acute lymphoblastic leukemia (ALL), both associated with a more favorable diagnosis. More than 40 different translocation partners have currently been identified making the RUNX1 break apart probe a valuable tool in molecular cytogenetics.

Two green-orange (2GO) fusion signals representing the two normal RUNX1 loci.
Aberrant Cell (typical results):
One green (1G), one orange (1O), and one green-orange (1GO) fusion signal, indicating a chromosome break in the RUNX1 locus.
