Ambry Genetics	RCV000163199	SCV000213721	likely benign	Hereditary cancer-predisposing syndrome	2014-09-24	criteria provided, single submitter	clinical testing	This alteration is classified as likely 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.
GeneDx	RCV000439758	SCV000512068	benign	not specified	2015-07-02	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.

Women's Health and Genetics/Laboratory Corporation of America, LabCorp	RCV000590422	SCV000694011	benign	not provided	2016-07-01	criteria provided, single submitter	clinical testing	Variant summary: The APC c.2232T>G (p.Ser744Ser) variant involves the alteration of a non-conserved nucleotide, resulting in a synonymous change. One in silico tool predicts a damaging outcome for this variant, and 1/5 splicing algorithms predict the loss of a cryptic splicing acceptor site. The variant of interest has not, to our knowledge, been evaluated for functional impact by in vivo/vitro studies. This variant was found in 10/120424 control chromosomes, predominantly observed in the African subpopulation at a frequency of 0.0009762 (10/10244). This frequency is about 14 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 African origin. In addition, one clinical diagnostic laboratory classified this variant as likely benign. Taken together, this variant is classified as Benign.
