Gene | PALB2 |
Variant | Q988* |
Impact List | nonsense |
Protein Effect | loss of function |
Gene Variant Descriptions | PALB2 Q988* results in a premature truncation of the Palb2 protein at amino acid 988 of 1186 (UniProt.org). Q988* confers a loss of function to the Palb2 protein as demonstrated by aberrant cytosolic accumulation in cultured cells (PMID: 28158555), and reduced protein stability and impaired homology-directed DNA repair activity compared to wild-type in cultured cells lacking Tp53 (PMID: 31757951). |
