GeneDx	RCV000211932	SCV000167014	benign	not specified	2014-01-06	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.
Ambry Genetics	RCV000128942	SCV000172817	benign	Hereditary cancer-predisposing syndrome	2014-12-13	criteria provided, single submitter	clinical testing	This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity.

Illumina Laboratory Services, Illumina	RCV000398735	SCV000452042	benign	APC-Associated Polyposis Disorders	2018-01-12	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 benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease.

Women's Health and Genetics/Laboratory Corporation of America, LabCorp	RCV000586387	SCV000694103	benign	not provided	2016-02-23	criteria provided, single submitter	clinical testing	Variant summary: The APC c.6921G>A variant affects a non-conserved nucleotide, resulting in a synonymous change at Ser2307. 5/5 Alamut algorithms predict no significant change to normal splicing. ESEfinder predicts a loss of binding motif for RNA splicing enhancer. These in silico predictions have not been verified with in vitro/in vivo functional studies. This variant was found in 169/120898 control chromosomes at a frequency of 0.0013979, which is about 23 times the maximal expected frequency of a pathogenic APC allele (0.0000602), suggesting this variant is benign. In addition, multiple clinical laboratories database classified this variant as benign. Taken together, this variant was classified as benign.

Department of Pathology and Laboratory Medicine, Sinai Health System	RCV001353599	SCV000591205	likely benign	Carcinoma of colon		no assertion criteria provided	clinical testing	The APC, c.6921G>A, p.Ser2307Ser variant is not expected to have clinical significance because it does not alter an amino acid residue and is not located near a splice junction. It is listed in dbSNP database (ID#: rs2229993) with a global minor allele frequency (MAF) of 0.001/3. It has been reported in the InSiGHT colon cancer database as a rare familial variant found in a proband with an attenuated colorectal phenotype and sebaceous cysts. The number of probands with the variant, was not provided. In addition, this variant is not of the type that is expected to cause the disorder. In summary, we cannot rule out the possibility that this variant may contribute to the phenotype in this individual, but based on the above information this variant is classified as predicted benign.
