The NM_000038.6(APC):c.5465T>A (p.Val1822Asp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a cumulative frequency of 0.781 (AC=1,257,991) in the gnomAD database across 1,611,172 control chromosomes, including 493,662 homozygotes. The grpmax filtering allele frequency (95% CI) is 0.952. In-silico predictor (REVEL) classifies this variant as likely benign. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. Variant has been reported in ClinVar as Benign/Likely Benign (★★★). Other variants at the same amino acid position have been reported in ClinVar (not pathogenic): p.V1822D: Benign (ClinVar VariationId 3304266, 1 star); p.V1822D: Uncertain_significance (ClinVar VariationId 3343773, 1 star); p.V1822E: Uncertain_significance (ClinVar VariationId 963607, 1 star); p.V1822G: Conflicting_classifications_of_pathogenicity (ClinVar VariationId 231079); p.V1822I: Uncertain_significance (ClinVar VariationId 3411135, 1 star); p.V1822= (synonymous): Likely_benign (ClinVar VariationId 2452708, 1 star); p.V1822= (synonymous): Benign/Likely_benign (ClinVar VariationId 3254437, 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.

ENSG00000258864 (HGNC:):

Classification according to ACMG Germline Pathogenicity v2019

Specifications for APC are available in the ClinGen Criteria Specification Registry and recommended for reference when assigning criteria.

Our verdict: Benign. The variant received -17 points.

• BP4: Computational evidence supports benign — no pathogenic computational or splicing signal (BP4); Splicing verdict: benign (Strong).; Germline computational verdict: benign (Supporting).
• BP6: ClinVar ≥3 stars benign — very strong (BP6); ClinVar germline classification: Benign/Likely Benign, 3 star(s).
• BA1: GnomAD effective popmax AF >5% — BA1 stand-alone benign; GnomAD reliable popmax AF = 0.9524 — exceeds 5%% threshold (BA1 applied)
