Illumina Laboratory Services, Illumina	RCV000350913	SCV000392602	benign	Stiff skin syndrome	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 benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease.

GeneDx	RCV000440739	SCV000512989	likely benign	not specified	2017-08-23	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.

ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories	RCV000755535	SCV000603632	likely benign	not provided	2017-05-02	criteria provided, single submitter	clinical testing	The FBN1 c.1371C>G;p.Arg457Arg variant has not been described in the literature, but has been reported to ClinVar (VariationID: 316386). The variant is listed in the dbSNP variant database (rs25436) with an allele frequency of 0.5% in East Asians and 0.038 percent overall in the Exome Aggregation Consortium. This is a silent variant, the nucleotide at this position is not well conserved across species, and computational programs (SpliceSiteFinder-like, MaxEntScan, NNSplice, GeneSplicer) predict this variant has no significant effect on mRNA splicing. Taken together, this variant is considered likely benign.
Ambry Genetics	RCV000386737	SCV000738857	likely benign	Familial thoracic aortic aneurysm and aortic dissection	2016-12-21	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.
