GeneDx RCV000236472 SCV000292453 likely benign not specified 2017-08-02 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.

It does not lie in a known MCR (mutation cluster region) located at exon 15 where pathogenic variants are clustered (PMIDs 1338904 and 18387968). This variant was found in 17/121710 control chromosomes, predominantly observed in the European (Non-Finnish) subpopulation at a frequency of 0.0002413 (16/66310). This frequency is about 3 times the estimated maximal expected allele frequency of a pathogenic APC variant (0.0000714), suggesting this is likely a benign polymorphism found primarily in the populations of European (Non-Finnish) origin. In a FAP family reported in literature, it was found in affected as well as unaffected members suggesting that it is unlikely to cause disease in the family (Gayther_1995). In addition, it was also found to co-occur with another pathogenic variant c.1312+3A>G in one sample reported n UMD database, further supporting a benign outcome. A diagnostic center and a reputable database have classified this variant as likely benign/benign. Taken together, this variant has been classified as Benign.

Illumina Clinical Services Laboratory,Illumina RCV001253953 SCV001429837 likely benign APC-Associated Polyposis Disorders 2018-01-13 criteria provided, single submitter clinical testing This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as likely benign is not then subjected to further curation. The score for this variant resulted in a classification of likely benign for this disease.
