Labcorp Genetics (formerly Invitae), Labcorp RCV004561518 SCV000647246 uncertain significance Familial adenomatous polyposis 1 2022-08-31 criteria provided, single submitter clinical testing ClinVar contains an entry for this variant (Variation ID: 469756). This sequence change replaces glycine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 857 of the APC protein (p.Gly857Val). 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. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. RNA analysis performed to evaluate the impact of this missense change on mRNA splicing indicates it does not significantly alter splicing (Invitae). 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.
GeneDx RCV003320680 SCV004025430 uncertain significance not provided 2024-06-12 criteria provided, single submitter clinical testing Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis indicates that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge
Ambry Genetics RCV003343912 SCV004059078 uncertain significance Hereditary cancer-predisposing syndrome 2023-08-17 criteria provided, single submitter clinical testing The p.G857V variant (also known as c.2570G>T), located in coding exon 15 of the APC gene, results from a G to T substitution at nucleotide position 2570. The glycine at codon 857 is replaced by valine, an amino acid with dissimilar properties. This amino acid position is not well conserved in available vertebrate species. In addition, in silico predictors for this gene do not accurately predict pathogenicity. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
Color Diagnostics, LLC DBA Color Health RCV003343912 SCV004360276 uncertain significance Hereditary cancer-predisposing syndrome 2022-11-16 criteria provided, single submitter clinical testing This missense variant replaces glycine with valine at codon 857 of the APC protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with APC-related disorders in the literature. This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance.
