Genes affected
PALB2 (HGNC:26144): (partner and localizer of BRCA2) This gene encodes a protein that may function in tumor suppression. This protein binds to and colocalizes with the breast cancer 2 early onset protein (BRCA2) in nuclear foci and likely permits the stable intranuclear localization and accumulation of BRCA2.

Familial cancer of breast Benign:2
Likely benign, reviewed by expert panel | curation | ClinGen Hereditary Breast, Ovarian and Pancreatic Cancer Variant Curation Expert Panel, ClinGen | Jun 15, 2023 | The c.212-33A>C variant in PALB2 is an intronic variant. BP7 applies because the threshold for the application of BP7 to deep intronic acceptor site variants is beyond position -21. The computational splicing predictor SpliceAI gives a score of 0.0 for acceptor loss suggesting that the variant has no impact on splicing. The highest population minor allele frequency in gnomAD v2.1.1 is 0.00006485 in the non-Finnish European population. (PM2_Supporting, BS1, and BA1 are not met). In summary, this variant meets the criteria to be classified as likely benign for autosomal dominant hereditary breast and pancreatic cancer and autosomal recessive FANCN based on the ACMG/AMP criteria applied, as specified by the HBOP VCEP.
