GeneDx RCV000183447 SCV000235907 uncertain significance not provided 2014-04-21 criteria provided, single submitter clinical testing p.Leu7His c.20 CTT>CAT in exon 1 of the EMD gene (NM_000117.2): A variant of unknown significance has been identified in the EMD gene. The L7H variant has not been published as a mutation or as a benign polymorphism to our knowledge. The L7H variant was not observed in approximately 6,000 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. Additionally, the L7H 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. Furthermore, in silico analysis predicts this variant is probably damaging to the protein structure/function. The vast majority of mutations in EMD, including the Met1 mutations, result in null alleles that abolish protein expression. The effect of L7H on protein expression is currently unknown. Therefore, based on the currently available information, it is unclear whether this variant is a pathogenic mutation or a rare benign variant. The variant is found in DCM-CRDM panel(s).
