RCV000199497 | SCV000250595 | uncertain significance | not provided | 2014-12-29 | criteria provided, single submitter | clinical testing | p.Gly1458Arg (GGT>CGT): c.4372 G>C in exon 31 of the MED12 gene (NM_005120.2) The G1458R variant of unknown significance in the MED12 gene has not been published as a mutation or been reported as a benign polymorphism to our knowledge. The G1458R variant was not observed in approximately 6000 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 G1458R 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. In silico analysis predicts this variant is probably damaging to the protein structure/function. Nevertheless, this substitution occurs at a position that is not conserved across species. Furthermore, no missense mutations in nearby residues have been reported in association with MED12-related disorders. 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 TAADV2-1 |
