Gene PIK3CA
Variant H1047X
Impact List missense
Protein Effect unknown
Gene Variant Descriptions PIK3CA H1047X indicates any Pik3ca missense mutation that results in the replacement of the histidine (H) at amino acid 1047 by a different amino acid. PIK3CA H1047X mutations are hotspot mutations that may result in increased Pik3ca kinase activity and cell transformation in culture (PMID: 15930273).
Associated Drug Resistance

PIK3CA mutant PIK3CA exon21 PIK3CA H1047X

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.
