Gene FGFR2
Variant L618F
Impact List missense
Protein Effect unknown
Gene Variant Descriptions FGFR2 L618F (corresponds to L617F in the canonical isoform) lies within the protein kinase domain of the Fgfr2 protein (UniProt.org). L618F in combination with FGFR2 H167_N173del results in constitutive FGFR2 signaling in culture, and has been shown to be associated with secondary resistance to FGFR inhibitors (PMID: 33926920), but has not been individually characterized and therefore, its effect on Fgfr2 protein function is unknown (PubMed, Dec 2023).
Associated Drug Resistance Y

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.
