GeneDx RCV000183669 SCV000236138 uncertain significance not provided 2013-07-09 criteria provided, single submitter clinical testing The Arg578Thr variant in the NEXN gene has not been reported as a disease-causing mutation or as a benign polymorphism to our knowledge. Arg578Thr results in a non-conservative amino acid substitution of a positively charged Arginine with a neutral, polar Threonine at a position that is class conserved across species. In silico analysis predicts Arg578Thr is damaging to the protein structure/function. The Arg578Thr variant was not observed with any significant frequency in approximately 6,000 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project. Nevertheless, no mutations in nearby residues have been reported in association with cardiomyopathy. With the clinical and molecular information available at this time, we cannot definitively determine if Arg578Thr in the NEXN gene, is a disease-causing mutation or a rare benign variant. The variant is found in DCM panel(s).
