Gene FGFR2
Variant E768*
Impact List nonsense
Protein Effect gain of function - predicted
Gene Variant Descriptions FGFR2 E768* results in a premature truncation of the Fgfr2 protein at amino acid 768 of 821 (UniProt.org). E768* is predicted to lead to a gain of Fgfr2 protein function as a corresponding mouse variant (E673*) activates FGFR2 signaling and promotes colony formation in cell culture, and leads to tumor formation in a mouse model (PMID: 35948633).

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.
