Germline mutations in the gene are associated with the Background: PALB2 genetic disorder Fanconi anaemia and increased predisposition to cancer. Disease-associated variants are mainly protein-truncating mutations, whereas a few missense substitutions are reported to perturb its interaction with breast cancer susceptibility proteins BRCA1 and BRCA2, which play essential roles in homology-dire...

Background: Germline mutations in the PALB2 gene are associated with the genetic disorder Fanconi anaemia and increased predisposition to cancer. Disease-associated variants are mainly protein-truncating mutations, whereas a few missense substitutions are reported to perturb its interaction with breast cancer susceptibility proteins BRCA1 and BRCA2, which play essential roles in homology-direct...

Through complete sequencing of the protein-coding genes in a patient with familial pancreatic cancer, we identified a germline, truncating mutation in PALB2 that appeared responsible for this patient's predisposition to the disease. Analysis of 96 additional patients with familial pancreatic cancer revealed three distinct protein-truncating mutations, thereby validating the role of PALB2 as a s...

Mutations of the PALB2 tumor suppressor gene in humans are associated with hereditary predisposition to breast and also some other cancers. In the present study, we have characterized mice deficient in Palb2. The data show that the Palb2((+/-)) mice are normal and fertile, and lack macroscopic tumors when followed up till the age of 8 months. Homozygous (HO) Palb2((-/-)) mice present with embry...

The partner and localizer of BRCA2 (PALB2) gene was recently identified as a BRCA2-interacting protein and subsequently shown to be a Fanconi anemia gene (FANCN). Disease-associated point mutations resulting in protein truncation have been found in BRCA1/2 mutation-negative breast cancer families identifying PALB2 as a susceptibility gene for breast cancer. Aberrant promoter hypermethylation is...

BACKGROUND The PALB2 gene, also known as FANCN, forms a bond and co-localizes with BRCA2 in DNA repair. Germline mutations in PALB2 have been identified in approximately 1% of familial breast cancer and 3-4% of familial pancreatic cancer. The goal of this study was to determine the prevalence of PALB2 mutations in a population of BRCA1/BRCA2 negative breast cancer patients selected from either ...

The deoxyribonucleic acid (DNA) damage response (DDR) is a major feature in the maintenance of genome integrity and in the suppression of tumorigenesis. PALB2 (Partner and Localizer of Breast Cancer 2 (BRCA2)) plays an important role in maintaining genome integrity through its role in the Fanconi anemia (FA) and homologous recombination (HR) DNA repair pathways. Since its identification as a BR...

BACKGROUND Germline mutations in PALB2 gene make a small contribution to heritable breast cancer susceptibility. A recent report has revealed that women with mutations in the PALB2 gene were more than nine times as likely to develop breast cancer compared to those without. The aim of this study is to understand the status of PALB2 mutations among Chinese high-risk breast cancer patients in a mu...

Mutations in breast cancer susceptibility gene 1 and 2 (BRCA1 and BRCA2) predispose individuals to breast and ovarian cancer development. We previously reported an in vivo interaction between BRCA1 and BRCA2. However, the biological significance of their association is thus far undefined. Here, we report that PALB2, the partner and localizer of BRCA2, binds directly to BRCA1, and serves as the ...
