Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV000590138 SCV000694005 uncertain significance not provided 2017-01-19 criteria provided, single submitter clinical testing Variant summary: The APC c.195G>C (p.Gln65His) variant involves the alteration of a non-conserved nucleotide. 3/4 in silico tools predict a damaging outcome for this variant (SNPs&GO not captured due to low reliability index). This variant is absent in 121020 control chromosomes. The variant of interest has not, to our knowledge, been reported in affected individuals via publications and/or reputable databases/clinical diagnostic laboratories; nor evaluated for functional impact by in vivo/vitro studies. Because of the absence of clinical information and the lack of functional studies, the variant is classified as a variant of uncertain significance (VUS) until additional information becomes available.
Invitae RCV003744600 SCV002219900 uncertain significance Familial adenomatous polyposis 1 2021-08-23 criteria provided, single submitter clinical testing This sequence change replaces glutamine with histidine at codon 65 of the APC protein (p.Gln65His). The glutamine residue is highly conserved and there is a small physicochemical difference between glutamine and histidine. This variant is not present in population databases (ExAC no frequency). 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: 495353). 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: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). 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.
