Gene FGFR3
Variant S131L
Impact List missense
Protein Effect unknown
Gene Variant Descriptions FGFR3 S131L lies within the extracellular domain of the Fgfr3 protein (UniProt.org). The functional effect of S131L is conflicting, as it results in decreased proliferation and cell viability compared to wild-type Fgfr3 in one study (PMID: 29533785), however, in another study, demonstrates increased cell proliferation under some cell culture conditions (PMID: 27053219), and therefore, its effect on Fgfr3 protein function is unknown.

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.
