Gene FGFR2
Variant M538I
Impact List missense
Protein Effect gain of function
Gene Variant Descriptions FGFR2 M538I (corresponds to M537I in the canonical isoform) lies within the protein kinase domain of the Fgfr2 protein (UniProt.org). M538I confers a gain of function to the Fgfr2 protein as demonstrated by increased Fgfr2 kinase activity (PMID: 32723837, PMID: 23908597) and enhanced cell proliferation in the presence of ligand in cell culture (PMID: 23908597), and has been associated with decreased sensitivity to some FGFR inhibitors (PMID: 23908597).

Filtering

  • Case insensitive filtering will display rows where any text in any cell matches the filter term
  • Simple literal full or partial string matches
  • Separate multiple filter terms with a spaces, order doesn't matter (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 a longer phrase which contains spaces "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.
