The PALB2 gene is associated with an increased risk for autosomal dominant breast and pancreatic cancer, and possibly ovarian cancer, in individuals who carry a single pathogenic PALB2 variant (PMID: 25099575, 17200668, 18628482). Additionally, the PALB2 gene is associated with autosomal recessive Fanconi anemia (MedGen UID: 372133).

Invitae tests that include this gene:
PALB2 is a tumor-suppressor gene that encodes the partner and localizer of BRCA2 protein, which plays a role in DNA damage repair, cell growth, and division. This protein binds to and colocalizes with the breast cancer 2 early onset protein (BRCA2) and permits the stable intranuclear localization and accumulation of BRCA2. Loss of PALB2 function due to pathogenic variants causes defective DNA repair, leading to accumulation of DNA damage, thereby increasing the risk of tumor formation.
Invitae is a College of American Pathologists (CAP)-accredited and Clinical Laboratory Improvement Amendments (CLIA)-certified clinical diagnostic laboratory performing full-gene sequencing and deletion/duplication analysis using next-generation sequencing technology (NGS).
Our sequence analysis covers clinically important regions of each gene, including coding exons, +/- 10 base pairs of adjacent intronic sequence, and select noncoding variants. Our assay provides a Q30 quality-adjusted mean coverage depth of 350x (50x minimum, or supplemented with additional analysis). Variants classified as pathogenic or likely pathogenic are confirmed with orthogonal methods, except individual variants that have high quality scores and previously validated in at least ten unrelated samples.
Our analysis detects most intragenic deletions and duplications at single exon resolution. However, in rare situations, single-exon copy number events may not be analyzed due to inherent sequence properties or isolated reduction in data quality. If you are requesting the detection of a specific single-exon copy number variation, please contact Client Services before placing your order.
