GeneDx RCV000235550 SCV000293107 uncertain significance not provided 2015-09-21 criteria provided, single submitter clinical testing The I597F variant has not been published as pathogenic, nor has it been reported as a benign polymorphism to our knowledge. It 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 substitution occurs at a position that is conserved across species. In silico analysis predicts this variant is probably damaging to the protein structure/function. Additionally, missense variants in nearby residues (N598K, R603C/H, R606H) have been reported in the Human Gene Mutation Database in association with SMARD1 (Stenson et al., 2014), supporting the functional importance of this region of the protein. However, the I597F variant is a conservative amino acid substitution, which is not likely to impact secondary protein structure as these residues share similar properties. Therefore, based on the currently available information, it is unclear whether this variant is a pathogenic variant or a rare benign variant.
