Invitae | RCV002532200 | SCV000812750 | uncertain significance | Familial adenomatous polyposis 1 | 2018-05-29 | 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 do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C25"). This variant has not been reported in the literature in individuals with APC-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces valine with alanine at codon 2194 of the APC protein (p.Val2194Ala). The valine residue is highly conserved and there is a small physicochemical difference between valine and alanine. |
Ambry Genetics | RCV002369819 | SCV002667142 | uncertain significance | Hereditary cancer-predisposing syndrome | 2022-02-16 | criteria provided, single submitter | clinical testing | The p.V2194A variant (also known as c.6581T>C), located in coding exon 15 of the APC gene, results from a T to C substitution at nucleotide position 6581. The valine at codon 2194 is replaced by alanine, an amino acid with similar properties. This amino acid position is conserved. 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. |
