PIK3CA hotspot mutation is well established as an oncogenic driver event in cancer and its durable and efficacious inhibition is a focus in the development and testing of clinical cancer therapeutics. However, hundreds of cancer-associated PIK3CA mutations remain uncharacterized, their sensitivity to PI3K inhibitors unknown. Here, describe a series of PIK3CA C-terminal mutations, primarily nucleotide insertions, that produce a frame-shifted protein product with an extended C terminus. We report that these mutations occur at a low fr
