GeneDx RCV000198368 SCV000250540 uncertain significance not provided 2015-07-30 criteria provided, single submitter clinical testing p.Glu1377Lys (GAG>AAG): c.4129 G>A in exon 31 of the LAMA4 gene (NM_002290.3). A variant of unknown significance has been identified in the LAMA4 gene. The E1377K variant has not been published as a mutation or as a benign polymorphism to our knowledge. The E1377K 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. The E1377K 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 addition, this substitution occurs at a position that is completely conserved across species. In silico analysis predicts this variant is probably damaging to the protein structure/function.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 CARDIOMYOPATH.
