Gene CHEK2
Variant K249N
Impact List missense
Protein Effect unknown
Gene Variant Descriptions CHEK2 K249N lies within the protein kinase domain of the Chek2 protein (UniProt.org). K249N has been identified in sequencing studies (PMID: 32183364), but has not been biochemically characterized and therefore, its effect on Chek2 protein function is unknown (PubMed, Apr 2026).

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.
