Gene PALB2
Variant Y551*
Impact List nonsense
Protein Effect loss of function
Gene Variant Descriptions PALB2 Y551* results in a premature truncation of the Palb2 protein at amino acid 551 of 1186 (UniProt.org). Y551* confers a loss of function to the Palb2 protein as demonstrated by loss of Brca2 and Rad51c binding and reduced Rad51 binding in cultured cells (PMID: 24141787), cell cycle defects (PMID: 31757951), and impaired homology-directed DNA repair activity compared to wild-type in cultured cells lacking Tp53 (PMID: 31636395, PMID: 31757951).

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.
