Impact List missense
Protein Effect gain of function
Gene Variant Descriptions FGFR2 F276C lies within the Ig-like C2-type domain 3 of the Fgfr2 protein (UniPort.org). F276C results in increased Fgfr2 expression, altered cellular localization, and ligand-independent Erk phosphorylation in culture (PMID: 30761385).

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.

Molecular Profile Indication/Tumor Type Response Type Therapy Name Approval Status Evidence Type Efficacy Evidence References
FGFR2 F276C intrahepatic cholangiocarcinoma predicted - sensitive Infigratinib Case Reports/Case Series Actionable In a Phase II trial, Truseltiq (infigratinib) treatment resulted in partial response after 2 months of therapy and response was maintained for 4 months in a patient with advanced intrahepatic cholangiocarcinoma harboring a FGFR2 F276C mutation, which is consistent with inhibition of Erk signaling in cholangiocarcinoma cells expressing FGFR2 F274C in culture (PMID: 30761385; NCT02150967). 30761385
FGFR2 F276C intrahepatic cholangiocarcinoma predicted - sensitive Pazopanib Case Reports/Case Series Actionable In a clinical case study, Votrient (pazopanib) treatment resulted in a partial response that continued for 11 months after starting treatment in a patient with intrahepatic cholangiocarcinoma harboring FGFR2 F276C (PMID: 34480077). 34480077
