GeneDx RCV000120030 SCV000149027 likely benign not specified 2017-10-18 criteria provided, single submitter clinical testing This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease.

Illumina Clinical Services Laboratory,Illumina RCV001153053 SCV001314301 uncertain significance APC-Associated Polyposis Disorders 2019-09-09 criteria provided, single submitter clinical testing This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. However, the evidence from the literature, in combination with allele frequency data from public databases where available, was not sufficient to rule this variant in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance.
Integrated Genetics/Laboratory Corporation of America RCV000120030 SCV001363502 benign not specified 2019-02-08 criteria provided, single submitter clinical testing Variant summary: APC c.7036C>T (p.Pro2346Ser) results in a non-conservative amino acid change located in the Adenomatous polyposis coli protein basic domain of the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.00035 in 275598 control chromosomes, predominantly at a frequency of 0.0074 within the Ashkenazi Jewish subpopulation in the gnomAD database. The observed variant frequency within Ashkenazi Jewish control individuals in the gnomAD database is approximately 104 fold of the estimated maximal expected allele frequency for a pathogenic variant in APC causing Familial Adenomatous Polyposis phenotype (7.1e-05), strongly suggesting that the variant is a benign polymorphism found primarily in populations of Ashkenazi Jewish origin. c.7036C>T has been reported in the literature in individuals affected with different types of cancer, including pancreatic cancer and breast and/or ovarian cancer (Young_2018, Mandelker_2017, Yadav_2017, Maxwell_2016, Grant_2015, Zhang_2015). These reports do not provide unequivocal conclusions about association of the variant with Familial Adenomatous Polyposis. A co-occurrence with another pathogenic variant has been reported in our internal database (APC c.1690C>T, p.Arg564*), providing supporting evidence for a benign role. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Seven ClinVar submissions from clinical diagnostic laboratories (evaluation after 2014) cite the variant as benign (1x), likely benign (2x) and uncertain significance (4x). Based on the evidence outlined above, the variant was classified as benign.
