GeneDx RCV000724937 SCV000279265 uncertain significance not provided 2018-03-12 criteria provided, single submitter clinical testing The E446K variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. The E446K variant was not observed with any significant frequency in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project. The E446K 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. However, this substitution occurs at a position that is not conserved, and Lysine has been seen at this position in evolution. 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.
