Invitae RCV003538496 SCV000768229 uncertain significance Familial adenomatous polyposis 1 2023-12-06 criteria provided, single submitter clinical testing This sequence change replaces glutamic acid, which is acidic and polar, with glutamine, which is neutral and polar, at codon 1886 of the APC protein (p.Glu1886Gln). This variant is present in population databases (rs587781400, gnomAD 0.0009%). 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: 537530). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt APC protein function with a negative predictive value of 95%. 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 RCV001024374 SCV001186377 uncertain significance Hereditary cancer-predisposing syndrome 2018-10-31 criteria provided, single submitter clinical testing The p.E1886Q variant (also known as c.5656G>C), located in coding exon 15 of the APC gene, results from a G to C substitution at nucleotide position 5656. The glutamic acid at codon 1886 is replaced by glutamine, an amino acid with highly similar properties. This amino acid position is well 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.
GeneDx RCV001550473 SCV001770804 uncertain significance not provided 2019-08-21 criteria provided, single submitter clinical testing Not observed at a significant allele frequency in large population cohorts (Lek 2016); In silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge
