NCIt definition : A fusion gene that results from an intrachromosomal deletion of the pseudoautosomal
region 1of Xp22.3 and Yp11.3 which fuses the noncoding exon 1 of the P2RY8 gene to
the entire coding region of the CRLF2 gene. This rearrangement is associated with
Down syndrome-associated acute lymphoblastic leukemia.;
NCIt note : The P2RY8/CRLF2 gene fusion causes aberrant expression of the CRLF2 gene.;
