Gene CTNNB1
Variant T42fs
Impact List frameshift
Protein Effect loss of function - predicted
Gene Variant Descriptions CTNNB1 T42fs results in a change in the amino acid sequence of the Ctnnb1 protein beginning at aa 42 of 781, likely resulting in premature truncation of the functional protein (UniProt.org). Due to the loss of all known functional domains (UniProt.org), T42fs is predicted to confer a loss of function to the Ctnnb1 protein.

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.
