Illumina Clinical Services Laboratory,Illumina RCV000245150 SCV000392149 uncertain significance Familial thoracic aortic aneurysm and aortic dissection 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, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease.
Illumina Clinical Services Laboratory,Illumina RCV000390288 SCV000392150 likely benign Geleophysic dysplasia 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.

GeneDx RCV000419193 SCV000513005 likely benign not specified 2018-01-04 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 RCV000419193 SCV000695595 likely benign not specified 2019-06-17 criteria provided, single submitter clinical testing Variant summary: FBN1 c.7056C>T alters a non-conserved nucleotide resulting in a synonymous change. 5/5 computational tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 4.8e-05 in 250820 control chromosomes. This frequency is not significantly higher than expected for a pathogenic variant in FBN1 causing Marfan Syndrome (4.8e-05 vs 0.00011), allowing no conclusion about variant significance. The variant of interest was identified in an individual with a likely pathogenic FBN1 variant, c.4794_4795insATAA (p.Pro1599fsX11 scored PrDV) (internal LCA). To our knowledge, no occurrence of c.7056C>T in individuals affected with Marfan Syndrome and no experimental evidence demonstrating its impact on protein function have been reported in literature. Five clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014, reporting the variant with conflicting assessments. Three laboratories have reported the variant as likely benign, while two others have classified it as uncertain significance. Based on the evidence outlined above, the variant was classified as likely benign.
