The invention provides PIK3CA (phosphatidylinositol-4,5-bisphosphate 3-kinase, catalytic subunit alpha) gene fusions, and fragments of those gene fusions. The invention further provides methods of diagnosing and treating diseases or disorders associated with PIK3CA fusions, such as conditions mediated by PIK3CA aberrant expression or activity, or overexpression of PIK3CA. |
