GeneDx RCV000198651 SCV000249837 likely pathogenic not provided 2014-08-20 criteria provided, single submitter clinical testing The I1491F variant has not been published as a mutation, nor has it been reported as a benign polymorphism to our knowledge. This variant was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. In silico analysis predicts this variant is probably damaging to the protein structure/function. Moreover, missense mutations in nearby residues (G1486C, G1489R, G1489E, G1492S) have been reported in association with EDS, supporting the functional importance of this region of the protein. However, the I1491F variant is a conservative amino acid substitution, which is not likely to impact secondary protein structure as these residues share similar properties. This substitution occurs at a position that is conserved across species. Therefore, based on the currently available information, it is unclear whether this variant is a pathogenic mutation or a rare benign variant. This variant was found in COL5A1,TAAD.
