Variant summary

Our verdict is The variant received 0 classification points (ACMG Germline Pathogenicity v2019): 1P and 1B. PM2_SupportingBP6

The NM_000038.6(APC):c.2627G>A (p.Arg876Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a cumulative frequency of 0.0000601 (AC=97) in the gnomAD database across 1,613,982 control chromosomes (no homozygotes observed). The grpmax filtering allele frequency (95% CI) is 0.0000625. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. Variant has been reported in ClinVar as Benign/Likely Benign (no review stars). Other variants at the same amino acid position have been reported in ClinVar (not pathogenic): p.R876G: Uncertain_significance (ClinVar VariationId 959507, 2 stars); p.R876L: Uncertain_significance (ClinVar VariationId 1020757, 1 star); p.R876P: Uncertain_significance (ClinVar VariationId 921047, 2 stars); p.R876= (synonymous): Benign/Likely_benign (ClinVar VariationId 469763, 2 stars) This exact variant is curated in the UniProt human variants database as Uncertain Significance; it is also listed as a COSMIC curated somatic variant.

Genes affected

APC (HGNC:583): (APC regulator of WNT signaling pathway) This gene encodes a tumor suppressor protein that acts as an antagonist of the Wnt signaling pathway. It is also involved in other processes including cell migration and adhesion, transcriptional activation, and apoptosis. Defects in this gene cause familial adenomatous polyposis (FAP), an autosomal dominant pre-malignant disease that usually progresses to malignancy. Mutations in the APC gene have been found to occur in most colorectal cancers, where disease-associated mutations tend to be clustered in a small region designated the mutation cluster region (MCR) and result in a truncated protein product.
