Gene CHEK2
Variant K135Nfs*26
Impact List frameshift
Protein Effect loss of function - predicted
Gene Variant Descriptions CHEK2 K135Nfs*26 indicates a shift in the reading frame starting at amino acid 135 and terminating 26 residues downstream causing a premature truncation of the 543 amino acid Chek2 protein (UniProt.org). K135Nfs*26 results in reduced Kap1 phosphorylation upon ionizing radiation in cell culture (PMID: 34903604), and therefore, is predicted to lead to a loss of Chek2 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.
