GeneDx RCV000181073 SCV000233349 likely benign not specified 2018-01-31 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.

Illumina Clinical Services Laboratory,Illumina RCV000148458 SCV000425505 likely benign Ehlers-Danlos syndrome, type 4 2018-03-15 criteria provided, single submitter clinical testing This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to determine this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign.

Integrated Genetics/Laboratory Corporation of America RCV000181073 SCV000695380 benign not specified 2019-04-01 criteria provided, single submitter clinical testing Variant summary: COL3A1 c.812G>A (p.Arg271Gln) results in a conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.0014 in 278388 control chromosomes, predominantly at a frequency of 0.0024 within the Non-Finnish European subpopulation in the gnomAD database. The observed variant frequency within Non-Finnish European control individuals in the gnomAD database is approximately 1920 fold of the estimated maximal expected allele frequency for a pathogenic variant in COL3A1 causing Aortopathy phenotype (1.3e-06), strongly suggesting that the variant is a benign polymorphism found primarily in populations of Non-Finnish European origin. The variant has been reported in patients with traumatic subarachnoid hemorrhage, familial abdominal aortic aneurysm and in two patients with clinical features of EhlersDanlos syndrome (Pickup _2011, van de Luijtgaarden_2015, Frank_2015). These reports however, do not provide unequivocal conclusions about association of the variant with Aortopathy. In a recent study examining a cohort of cases received to interpret variants originally identified by an outside laboratory, this variant was reportedly identified with another (identity not provided) mutation in 5 out of 14 unrelated probands, was inherited from an unaffected parent in one case and was reportedly found to have a normal type III collagen analysis in one patient (Pepin_2015). To our knowledge, no other experimental evidence demonstrating an impact on protein function has been reported. Nine clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All laboratories classified the variant as benign (X2)/likely benign (X7). Based on the evidence outlined above, the variant was classified as benign.
