A SNaPshot assay for the rapid and simple detection of four common hotspot codon mutations in the PIK3CA gene

Abstract
Activating mutations in the PIK3CA gene have been identified in a variety of human malignancies and are commonly detected in hotspot codons located in the helical and kinase domains in exons 9 and 20. Existing methodologies for the detection of PIK3CA mutations are time-consuming and/or expensive. In the present study we describe the first application of a PIK3CA SNaPshot assay to the screening of frequent mutations in these exons.
