Cancer-specific mutations in phosphatidylinositol 3-kinase.

Abstract excerpt

Cancer-specific mutations in the catalytic subunit of phosphatidylinositol 3-kinase (PI3K) p110 alpha occur in diverse tumors in frequencies that can exceed 30%. The majority of these mutations map to one of three hot spots in the gene, and the rest are distributed over much of the PI3K coding sequence. Most of the cancer-specific mutations induce a gain of function that results in oncogenicity, elevated lipid...
