NCIt definition : A fusion gene that results from a rearrangement of chromosomes 15 and 19 which fuses
the 5' end of the PIK3R2 gene to the 3' end of the USP8 gene. This rearrangement may
be associated with chronic myeloproliferative disorder.;
NCIt note : This fusion gene may also harbor a PIK3R2 gene variant that substitutes an alanine
for a serine in a site that regulates the lipid kinase activity of the phosphatidylinositol
3-kinase regulatory subunit alpha protein. (Oncogene. 1998; 16: 1767-1772.);
