Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV000588294 SCV000695355 benign not provided 2016-04-04 criteria provided, single submitter clinical testing Variant Summary: The c.1617C>T variant involves the alteration of a non-conserved nucleotide resulting in a synonymous change. 5/5 in silico tools via Alamut predict no significant effect on splicing. The variant was observed in the large, broad control population, ExAC with, an allele frequency of 0.007%. This frequency exceeds the maximum expected allele frequency for a pathogenic COL3A1 variant (0.0001%), suggesting this is a benign polymorphism. The variant of interest has not, to our knowledge, been reported in affected individuals via publications and/or reputable databases/clinical laboratories; nor evaluated for functional impact by in vivo/vitro studies. Taken together, this variant has been classified as Benign.

Ambry Genetics RCV000772005 SCV002705816 likely benign Familial thoracic aortic aneurysm and aortic dissection 2019-08-20 criteria provided, single submitter clinical testing This alteration is classified as likely benign based on a combination of the following: 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.
