GeneDx RCV000199563 SCV000249932 uncertain significance not provided 2014-09-03 criteria provided, single submitter clinical testing The c.4561_4569delACTGGTCCT variant has not been published as a mutation, nor has it been reported as a benign polymorphism to our knowledge. The c.4561_4569delACTGGTCCT 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. This variant results in an in-frame deletion of three amino acid residues in the COL5A1 gene, effectively ablating one Gly-X-Y repeat in the triple helical region. Other mutations in the COL5A1 gene that cause in-frame deletions have been reported in association with Ehlers-Danlos syndrome. Although c.4561_4569delACTGGTCCT is located in the triple helical region, these residues are not completely 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.
