XL MECOM 3q26 consists of an orange-labeled probe hybridizing proximal to the MECOM gene region at 3q26.2 and a green-labeled probe hybridizing distal to the MECOM gene region also spanning a distal part of the gene region at 3q26.2.
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.
Myelodysplastic syndromes and myeloproliferative disorders are associated with deregulated production of myeloid cells. According to WHO classification (2008), cytogenetic aberrations are observed in about 50% of MDS cases. The most common aberrations are 5q-, 7/7q-, trisomy 8, del(20q), and inv(3) or t(3;3).
Chromosomal translocations involving the EVI1 locus are a recurrent finding in myeloid leukemia and are associated with poor prognosis. Two common recurrent rearrangements affect the 3q26 locus. One is the inv(3)(q21q26) and the translocation t(3;3)(q21;q26), in which EVI1 overexpression is caused by juxtaposition of the EVI1 gene to enhancer elements of the Ribophorin gene at 3q21. EVI1 activation is also observed in the translocations t(3;12)(q26;p13) and t(3;21)(q26;q22) and is due to generation of the fusion genes ETV6/EVI1 and RUNX1/EVI1, respectively.
Normal Cell:
Two green-orange (2GO) fusion signals representing the two normal MECOM loci.
Aberrant Cell (typical results):
One green (1G), one orange (1O), and one green-orange (1GO) fusion signal, indicating a chromosome break in the MECOM locus.
Aberrant Cell (typical results):
One green (1G) and two green-orange (2GO) fusion signals, indicating a variant chromosome break at a more distal region of the MECOM locus.
