Gene PIK3CA
Variant E110del
Impact List deletion
Protein Effect gain of function - predicted
Gene Variant Descriptions PIK3CA E110del results in the deletion of an amino acid in the Pik3ca protein at amino acid 110 (UniProt.org). E110del results in Akt phosphorylation similar to wild-type Pik3ca (PMID: 34779417), but leads to increased cell proliferation and migration (PMID: 34779417) and transformation ability in several different cell lines in culture (PMID: 29533785, PMID: 34779417), and therefore, is predicted to lead to a gain of Pik3ca protein function.

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.
