GeneDx RCV000224083 SCV000250602 uncertain significance not provided 2015-11-20 criteria provided, single submitter clinical testing p.Thr617Ala (ACT>GCT): c.1849 A>G in exon 13 of the MED12 gene (NM_005120.2) The T617A variant of unknown significant in the MED12 gene has not been published as a mutation, nor has it been reported as a benign polymorphism to our knowledge. The T617A variant was not observed in approximately 6,100 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. The T617A variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. This substitution occurs at a position that is conserved across species. In silico analysis predicts this variant is probably damaging to protein structure/function. However, no missense mutations in nearby residues have been reported in association with LS or related disorders indicating that this region of the protein may be tolerant of change. 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 TAAD
