Invitae RCV003537449 SCV001209324 uncertain significance Familial adenomatous polyposis 1 2022-04-29 criteria provided, single submitter clinical testing This sequence change replaces cysteine, which is neutral and slightly polar, with tyrosine, which is neutral and polar, at codon 483 of the APC protein (p.Cys483Tyr). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with APC-related conditions. ClinVar contains an entry for this variant (Variation ID: 842960). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C65"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
Ambry Genetics RCV003160340 SCV003899662 uncertain significance Hereditary cancer-predisposing syndrome 2022-12-09 criteria provided, single submitter clinical testing The p.C483Y variant (also known as c.1448G>A), located in coding exon 11 of the APC gene, results from a G to A substitution at nucleotide position 1448. The cysteine at codon 483 is replaced by tyrosine, an amino acid with highly dissimilar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
