Gene POLE
Variant A456P
Impact List missense
Protein Effect unknown
Gene Variant Descriptions POLE A456P lies within the exonuclease domain of the Pole protein (PMID: 29352080). A456P has been identified in the scientific literature (PMID: 31829442, PMID: 31624068, PMID: 34910396), but has not been biochemically characterized, and therefore, its effect on Pole protein function is unknown (PubMed, Sep 2025).

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.

POLE mutant Advanced Solid Tumor predicted - sensitive unspecified PD-1 antibody Clinical Study - Cohort Actionable In a clinical study, immune checkpoint inhibitor (ICI) treatment, including CTLA4, PD-1, and PD-L1-targeting antibodies, resulted in prolonged overall survival (34 vs 18 months, p=0.004) in patients with advanced solid tumors harboring POLE or POLD1 mutations compared to wild-type patients, and POLE/POLD1 mutation served as a predictor of response to ICI (p=0.047, HR=1.41) independent of MSI-H status (PMID: 31415061). 31415061
