The c.3249G>C (p.Glu1083Asp) variant in PALB2 is a missense variant predicted to cause substitution of glutamic acid by aspartic acid at amino acid 1083 (p.Glu1083Asp). This variant has a gnomAD v2.1.1 filtering allele frequency of 0.001331 in the Latino/Admixed American population, which is higher than the HBOP VCEP threshold (>0.001) for BA1, and therefore meets this criterion. This variant is functional in multiple protein assays; however, due to a lack of positive missense controls with known clinical impact, these assays do not meet the requirements for use by the HBOP VCEP (PMID: 31636395). PALB2, in which the variant was identified, is defined by the HBOP VCEP as a gene for which primarily truncating variants are known to cause disease. In summary, this variant meets the criteria to be classified as 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.
