Gene TP53
Variant S90fs
Impact List frameshift
Protein Effect loss of function - predicted
Gene Variant Descriptions TP53 S90fs results in a change in the amino acid sequence of the Tp53 protein beginning at 90 of 393, likely resulting in premature truncation of the functional protein (UniProt.org). S90fs has not been biochemically characterized however, due to the effects of truncation mutations downstream of S90 (PMID: 31081129, PMID: 34045312), is predicted to lead to a loss of Tp53 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.
