GeneDx RCV000197124 SCV000250173 uncertain significance not provided 2015-12-11 criteria provided, single submitter clinical testing p.Ser893Arg (AGC>AGG): c.2679 C>G in exon 21 of the FBN2 gene (NM_001999.3) The S893R variant in the FBN2 gene has not been reported as a disease-causing mutation or as a benign polymorphism to our knowledge. S893R results in a semi-conservative amino acid substitution of one small, neutral residue (Ser) being replaced by a larger, positively charged residue (Arg) at a position that is conserved across species. The S893R 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 S893R is damaging to the protein structure/function. However, missense mutations in nearby residues have not been reported, indicating this region of the protein may tolerate change. In summary, while S893R is a good candidate for a disease-causing mutation, with the clinical and molecular information available at this time we cannot unequivocally determine the clinical significance of this variant. This variant was found in TAAD
