Gene FBXW7
Variant D550Mfs*6
Impact List frameshift
Protein Effect unknown
Gene Variant Descriptions FBXW7 D550Mfs*6 indicates a shift in the reading frame starting at amino acid 550 and terminating 6 residues downstream causing a premature truncation of the 707 amino acid Fbxw7 protein (UniProt.org). D550Mfs*6 has been identified in sequencing studies (PMID: 26960398), but has not been biochemically characterized and therefore, its effect on Fbxw7 protein function is unknown (PubMed, Feb 2025).

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.
