NCIt definition : A fusion gene that results from a chromosomal translocation t(1;3)(p36;q23-25) which
fuses the first 2, 3 or 4 exons of the WWTR1 gene to the upstream side of either exon
8 or exon 9 of the CAMTA1 gene. This fusion is associated with epithelioid hemangioendothelioma.;
NCIt note : The WWTR1/CAMTA1 fusion has not been detected in any of the morphological mimics of
epithelioid hemangioendothelioma, such as epithelioid hemangioma, epithelioid angiosarcoma,
or pseudomyogenic hemangioendothelioma. The reciprocal CAMTA1/WWTR1 transcript has
not been described.;
