Gene BRAF
Variant D594N
Impact List missense
Protein Effect loss of function - predicted
Gene Variant Descriptions BRAF D594N lies within the protein kinase domain of the Braf protein (UniProt.org). D594N leads to activation of Erk signaling through CRAF but results in impaired Braf kinase activity in cell culture (PMID: 28783719) and decreased transformation ability compared to wild-type Braf in one of two cell lines in culture (PMID: 29533785), and therefore, is predicted to lead to a loss of Braf 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.
