Gene FGFR3
Variant H284fs
Impact List frameshift
Protein Effect gain of function - predicted
Gene Variant Descriptions FGFR3 H284fs results in a change in the amino acid sequence of the Fgfr3 protein beginning at aa 284 of 806, likely resulting in premature truncation of the functional protein (UniProt.org). H284fs results in proliferation similar to wild-type Fgfr3 in a competition assay but increased transformation activity in cultured cells (PMID: 34272467), 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.
