Variant summary

Our verdict is Likely pathogenic. The variant received 9 ACMG points: 9P and 0B. PVS1PM5_Supporting

This summary comes from the ClinGen Evidence Repository: The c.3362del (p.Gly1121fs) variant in PALB2 is a frameshift variant that may cause a premature stop codon that is predicted to escape nonsense mediated decay; however, it is a truncation of a functionally important region (removes amino acids 1123-1187) in a gene where loss-of-function is an established disease mechanism. This alteration results in a termination codon upstream of the most C-terminal pathogenic alteration (PALB2 p.Tyr1183*) as classified by the HBOP VCEP, and is expected to be more deleterious. This variant has a minor allele frequency in gnomAD v2.1.1 of 0.000003979 in the non-Finnish European population (PM2_Supporting, BS1, and BA1 are not met). In summary, this variant meets criteria to be classified likely pathogenic 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.

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.
