Gene FGFR3
Variant K652E
Impact List missense
Protein Effect gain of function - predicted
Gene Variant Descriptions FGFR3 K652E (corresponds to K650E in the canonical isoform) lies within the protein kinase domain of the Fgfr3 protein (UniProt.org). K652E results in constitutive phosphorylation of Src, Akt and Erk phosphorylation similar to wild-type Fgfr3, and anchorage-independent growth in cultured cells (PMID: 32370101), and has been demonstrated to induce transformation of mouse fibroblasts, but has a lesser degree of signaling and phenotypic effect in immortalized normal human urothelial cells (PMID: 19749790), and therefore, is predicted to lead to a gain of Fgfr3 protein function.

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.
