RCV000498896 | SCV000590593 | uncertain significance | not provided | 2018-06-25 | criteria provided, single submitter | clinical testing | A variant of uncertain significance has been identified in the GRIN2A gene. The L73M variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. The L73M variant is not observed at a significant frequency in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). The L73M variant is a conservative amino acid substitution, which is not likely to impact secondary protein structure as these residues share similar properties. This substitution occurs at a position where amino acids with similar properties to Leucine are tolerated across species. However, in silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. Therefore, based on the currently available information, it is unclear whether this variant is a pathogenic variant or a rare benign variant. |
