| titleOfInvention | Method Of Determining PIK3CA Mutational Status In A Sample |
| abstract | An ultra-sensitive, specific methodology for detecting PIK3CA mutations in biological samples of cancer patients, comprises a combination of allele-specific, asymmetric rapid PCR and melting analysis in a DNA sample from Circulating Tumor Cells, cell-free DNA in plasma/serum, or Formalin-Fixed Paraffin-Embedded tissues. Using the allele-specific primers for hotspot mutations in exons 9 and 20 (E545K and H1047R), detection can enhance amplification of mutant PIK3CA allele sequence, whereas presence of corresponding competitive blocking unlabeled probes for each exon can avoid non-specific amplification of wild-type PIK3CA sequence increasing the sensitivity and the specificity of method. The mutational detection is completed with melting curve analysis of the unlabeled probe and DNA template of the mutant PIK3CA sequence. Evaluation of PIK3CA mutational status on CTC in peripheral blood and cfDNA in plasma/serum of patients has potential for clinical applications and therapeutic interventions, since presence of PIK3CA mutations is associated with response to molecular targeted therapies. |
