Invitae RCV003652101 SCV001418642 uncertain significance Familial adenomatous polyposis 1 2021-02-27 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: "Possibly Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with APC-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces aspartic acid with asparagine at codon 156 of the APC protein (p.Asp156Asn). The aspartic acid residue is highly conserved and there is a small physicochemical difference between aspartic acid and asparagine.

Ambry Genetics RCV003346410 SCV004059104 uncertain significance Hereditary cancer-predisposing syndrome 2023-08-29 criteria provided, single submitter clinical testing The p.D156N variant (also known as c.466G>A), located in coding exon 4 of the APC gene, results from a G to A substitution at nucleotide position 466. The aspartic acid at codon 156 is replaced by asparagine, an amino acid with highly 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.
