NCIt definition : A fusion gene that results from a chromosomal translocation t(11;19)(q13;p13) which
places the CCND1 gene on the 5' side of the FSTL3 gene. This rearrangement may be
associated with B-cell chronic lymphocytic leukemia.;
NCIt note : This translocation disrupts the upstream regulatory region for the FSTL3 gene, which
causes aberrant expression of follistatin-related protein 3.;
