Gene Variant Descriptions | PALB2 R37H lies within the DNA-binding, and BRCA1 and RAD51-interacting regions of the Palb2 protein (UniProt.org). R37H results in decreased Brca1 binding and recruitment to DNA damage sites (PMID: 31757951), reduced Rad51 foci formation and intensity (PMID: 31586400), impaired homology-directed DNA repair activity, and failure to rescue PARP inhibitor sensitivity in PALB2-null cells in culture (PMID: 28319063, PMID: 31586400, PMID: 31757951), but in other studies demonstrates Brca1 binding and recruitment to DNA damage sites similar to wild-type Palb2 (PMID: 28319063, PMID: 31586400), and homology-directed DNA repair similar to wild-type in a reporter assay (PMID: 33964450), and therefore, its effect on Palb2 protein function is unknown. |
