InSiGHT Hereditary Colorectal Cancer/Polyposis VCEP

The c.2476T>G variant in APC is a missense variant predicted to cause a substitution of leucine by valine at amino acid position 826 (p.Leu826Val). The highest population minor allele frequency in gnomAD v2.1.1 is 0.1576% in the non-cancer African/African American population, which is higher than the ClinGen InSiGHT Hereditary Colorectal Cancer/Polyposis Variant Curation threshold (>0.1%) for BA1, and therefore meets this criterion (BA1). Additionally, APC is defined by the ClinGen InSiGHT Hereditary Colorectal Cancer/Polyposis Variant Curation Expert Panel as a gene for which primarily truncating variants are known to cause disease (BP1). Multiple lines of computational evidence suggest no splicing impact. In summary, this variant meets the criteria to be classified as Benign for FAP. ACMG/AMP criteria applied, as specified by the ClinGen/InSiGHT Hereditary Colorectal Cancer/Polyposis Expert Panel: BA1, BP1 (VCEP specifications version 1; date of approval: 12/12/2022).

BA1

The highest population minor allele frequency in gnomAD v2.1.1 is 0.1576% in African/African American population, which is higher than the ClinGen InSiGHT Hereditary Colorectal Cancer/Polyposis Variant Curation threshold (>0.1%) for BA1, and therefore meets this criterion (BA1).

BP1

APC, in which the variant was identified, is defined by the ClinGen InSiGHT Hereditary Colorectal Cancer/Polyposis VCEP as a gene for which primarily truncating variants are known to cause disease (BP1).

PP3

Multiple lines of computational evidence suggest no splicing impact (SpliceAI and varSEAK).
