Variant Q546R
Impact List missense
Protein Effect gain of function
Gene Variant Descriptions PIK3CA Q546R lies within the PIK helical domain of the Pik3ca protein (UniProt.org). Q546R results in increased cell proliferation, migration, and Akt phosphorylation (PMID: 34779417) and increased cell survival and transforming ability in culture (PMID: 26627007, PMID: 29533785, PMID: 34779417).

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.
