InSiGHT Hereditary Colorectal Cancer/Polyposis VCEP

The c.1746A>G (p.Glu582=) variant in APC is a synonymous (silent) variant that is not predicted to impact splicing (BP4, BP7). This variant has been observed in a heterozygous state in 12 unrelated healthy adult individuals worth 12 (≥ 10) healthy individual points in total (BS2; Ambry internal data). The highest population minor allele frequency of this variant in gnomAD v2.1.1 (non-cancer) is 0.0001148 in African/African American population, which is higher than the ClinGen InSiGHT Hereditary Colorectal Cancer/Polyposis threshold (≥ 0.0001) for BS1, and therefore meets this criterion (BS1). In summary, this variant meets the criteria to be classified as Benign for FAP based on the ACMG/AMP criteria applied, as specified by the ClinGen InSiGHT Hereditary Colorectal Cancer/Polyposis Variant Curation Expert Panel: BS1, BS2, BP4, and BP7 (VCEP specifications version 1; date of approval: 12/12/2022).

BS1

The highest population minor allele frequency of the variant c.1746A>G in gnomAD v2.1.1 (non-cancer) is 0.0001148 (1/8712 alleles) in African/African American population, which is higher than the ClinGen InSiGHT Hereditary Colorectal Cancer/Polyposis threshold threshold (≥ 0.0001) for BS1, and therefore meets this criterion (BS1).

BS2

This variant has been observed in heterozygous state in 12 healthy unrelated adult individuals worth 12 (≥ 10) healthy individual points in total (BS2; Ambry internal data).

BP7

The c.1746A>G (p.Glu582=) variant is a synonymous (silent) variant that is not predicted by MaxEntScan, SpliceAI and varSEAK to impact splicing (BP4, BP7).

BP4

The results from 3 in silico splicing predictors (MaxEntScan, SpliceAI, varSEAK) support that this variant does not affect splicing (BP4).
