| Protein Effect | loss of function |
| Gene Variant Descriptions | PALB2 I944N lies within WD repeat 2 of the Palb2 protein (UniProt.org). I944N confers a loss of function to the Palb2 protein as demonstrated by decreased protein stability (PMID: 31757951), reduced Brca2 and Rad51 binding, recruitment to DNA damage sites, and Rad51 foci formation, aberrant cytosolic accumulation (PMID: 31636395), and loss of homology-directed DNA repair activity in cultured cells (PMID: 31636395, PMID: 31757951). |
