| Invitae | RCV000685984 | SCV000813487 | uncertain significance | Familial adenomatous polyposis 1 | 2018-12-10 | criteria provided, single submitter | clinical testing | This sequence change replaces lysine with arginine at codon 1363 of the APC protein (p.Lys1363Arg). The lysine residue is highly conserved and there is a small physicochemical difference between lysine and arginine. This variant is not present in population databases (ExAC no frequency). This variant has been observed in an individual undergoing Lynch syndrome testing (PMID: 25980754). ClinVar contains an entry for this variant (Variation ID: 482274). 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 disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. 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. |
