PALB2 Gene Function

Partner And Localizer Of BRCA2

ProteinCurated

Overview

PALB2 connects BRCA1 with BRCA2 and helps position the BRCA2–RAD51 machinery at DNA double-strand breaks. Pathogenic germline variants can increase breast and pancreatic cancer risk and may contribute to homologous-recombination deficiency after biallelic loss.

Common Questions About PALB2

What does PALB2 do?

PALB2 participates in Homologous recombination, DNA double-strand break repair, Fanconi anaemia pathway. PALB2 connects BRCA1 with BRCA2 and helps position the BRCA2–RAD51 machinery at DNA double-strand breaks. Pathogenic germline variants can increase breast and pancreatic cancer risk and may contribute to homologous-recombination deficiency after biallelic loss.

Why is PALB2 relevant to cancer research?

Its reported relevance includes Hereditary breast cancer, Pancreatic cancer predisposition, Fanconi anaemia. The exact alteration, assay and disease context determine what a result can support.
