NCIt definition : A fusion gene that results from a chromosomal translocation t(12;22)(q13;q12) which
fuses the first 7 or 8 exons of the EWSR1 gene on the 5' side of exon 4 or 5 of the
ATF1 gene. This rearrangement is associated with both malignant clear cell sarcoma
of the soft tissue and angiomatoid fibrous histiocytoma.;
NCIt note : There are at least seven EWSR1/ATF1 fusion gene variants. (Atlas of Genetics and Cytogenetics
