NCIt definition : A fusion gene that results from a genetic translocation event which fuses the 5' end
of the androgen-regulated TMPRSS2 gene with the entire coding region of the ERG gene.
The androgen-dependent expression of this fusion gene results in overexpression of
ERG activity.;
NCIt note : This gene fusion was the first ever discovered in a solid tumor. It is also a biomarker
for Prostate Cancer. 7 October, NCI Cancer Bulletin 5, 20 (2008);
