| Gene | PALB2 |
| Variant | Q775* |
| Impact List | nonsense |
| Protein Effect | loss of function |
| Gene Variant Descriptions | PALB2 Q775* results in a premature truncation of the Palb2 protein at amino acid 775 of 1186 (UniProt.org). Q775* retains DNA binding in culture (PMID: 24485656), but confers a loss of function to the Palb2 protein as demonstrated by loss of binding with Poln, decreased enhancement of Poln DNA synthesis and Poln foci formation (PMID: 24485656), and decreased Brca2 and Rad51 binding and reduced DNA damage response in cultured cells (PMID: 28158555). |
