Invitae | RCV003536039 | SCV000956462 | uncertain significance | Familial adenomatous polyposis 1 | 2021-12-23 | criteria provided, single submitter | clinical testing | 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. 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: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 659039). This variant has not been reported in the literature in individuals affected with APC-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces isoleucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 2111 of the APC protein (p.Ile2111Val). |

RCV001180712 | SCV001345709 | uncertain significance | Hereditary cancer-predisposing syndrome | 2022-03-18 | criteria provided, single submitter | clinical testing | This missense variant replaces isoleucine with valine at codon 2111 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 hereditary cancer 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. |
Ambry Genetics | RCV001180712 | SCV002657268 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-05-31 | criteria provided, single submitter | clinical testing | The p.I2111V variant (also known as c.6331A>G), located in coding exon 15 of the APC gene, results from an A to G substitution at nucleotide position 6331. The isoleucine at codon 2111 is replaced by valine, an amino acid with highly similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
