Gene Variant Descriptions PIK3CA mutant indicates an unspecified mutation within the PIK3CA gene.
Associated Drug Resistance
Category Variants Paths

Filtering

  • Case insensitive filtering will display rows if any text in any cell matches the filter term
  • Use simple literal full or partial string matches
  • Separate multiple filter terms with a space. Any order may be used (i. e. a b c and c b a are equivalent )
  • Filtering will only apply to rows that are already loaded on the page. Filtering has no impact on query parameters.
  • Use quotes to match on a longer phrase with spaces (i.e. "mtor c1483f")

Sorting

  • Generally, the default sort order for tables is set to be first column ascending; however, specific tables may set a different default sort order.
  • Click on any column header arrows to sort by that column
  • Hold down the Shift key and click multiple columns to sort by more than one column. Be sure to set ascending or descending order for a given column before moving on to the next column.

CDKN2A mut PIK3CA mut breast cancer sensitive Sapanisertib Preclinical Actionable In a preclinical study, a breast cancer cell line harboring mutations in PIK3CA and CDKN2A demonstrated sensitivity to Sapanisertib (MLN0128) in culture (PMID: 25261369). 25261369
PIK3CA mut PTEN loss breast cancer resistant Alpelisib Case Reports/Case Series Actionable In a clinical case study, a breast cancer patient harboring a PIK3CA mutation developed resistance to Alpelisib (BYL719) treatment and progressive disease after initial response, accompanied by a loss of PTEN, and the corrresponding patient-derived xenograft model demonstrated resistance to Alpelisib (BYL719)-induced inhibition of tumor growth (PMID: 25409150). detail... 25409150
PIK3CA mut PTEN loss breast cancer sensitive Buparlisib Preclinical - Pdx Actionable In a preclinical study, Buparlisib (BKM120) inhibited Akt signaling and growth in a PDX model of breast cancer cells harboring a PIK3CA mutation and PTEN loss ( Cancer Res October 1, 2014 74; LB-327 ). detail...
PIK3CA mut PTEN loss breast cancer sensitive Alpelisib + AZD6482 Preclinical - Pdx Actionable In a preclinical study, AZD6482 and Alpelisib (BYL719) combination treatment inhibited Akt signaling and growth in a breast cancer patient-derived xenograft (PDX) model harboring a PIK3CA mutation and PTEN loss (Cancer Res October 1, 2014 74; LB-327). detail...
PIK3CA mut PTEN loss prostate cancer sensitive PKI-179 Preclinical - Cell culture Actionable In a preclinical study, PKI-179 inhibited growth of prostate cancer cells harboring PIK3CA mutations and PTEN loss in culture (PMID: 20797855). 20797855
FGFR1 over exp PIK3CA mut estrogen-receptor positive breast cancer sensitive Alpelisib + Lucitanib Preclinical - Cell culture Actionable In a preclinical study, an estrogen-receptor positive breast cancer cell line over expressing FGFR1 and expressing a PIK3CA mutation demonstrated sensitivity to the combination of Alpelisib (BYL719) and Lucitanib (E-3810) in culture (PMID: 27126994). 27126994
BRAF V600E PIK3CA mut colorectal cancer sensitive ASN003 Preclinical - Cell line xenograft Actionable In a preclinical study, a colorectal cancer cell line xenograft model co-harboring BRAF V600E and a PIK3CA mutation demonstrated tumor growth inhibition when treated with ASN003 (Mol Cancer Ther 2015;14(12 Suppl 2):Abstract nr B100). detail...
