Gene PALB2
Variant L1027R
Impact List missense
Protein Effect loss of function
Gene Variant Descriptions PALB2 L1027R lies within WD repeat 4 of the Palb2 protein (UniProt.org). L1027R results in decreased Palb2 protein stability, loss of nuclear localization, impaired homology-directed DNA repair activity in cultured cells, and confers sensitivity to PARP inhibition in PALB2-deficient cells (PMID: 33811135).
Associated Drug Resistance
Category Variants Paths

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.
