Gene PIK3CA
Variant E545X
Impact List missense
Protein Effect unknown
Gene Variant Descriptions PIK3CA E545X indicates any Pik3ca missense mutation that results in the replacement of the glutamic acid (E) at amino acid 545 by a different amino acid. PIK3CA E545X mutations are hotspot mutations that may result in increased Pik3ca kinase activity (PMID: 15930273).
Associated Drug Resistance

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.
