GeneDx RCV000183658 SCV000236127 uncertain significance not provided 2013-11-27 criteria provided, single submitter clinical testing p.Ser365Cys (TCT>TGT): c.1094 C>G in exon 10 of the NEXN gene (NM_144573.3). The Ser365Cys variant in the NEXN gene has not been reported as a disease-causing mutation or as a benign polymorphism to our knowledge. The Ser365Cys variant is a non-conservative amino acid substitution as these residues differ in polarity, charge, size and/or other properties and is more likely to impact secondary structure. In silico analysis predicts Ser365Cys is probably damaging to the protein structure/function. In addition, the Ser365Cys variant was not observed in approximately 5,800 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. Nevertheless, no mutations affecting nearby residues have been reported in association with cardiomyopathy, indicating this region of the protein may be tolerant of change. With the clinical and molecular information available at this time, we cannot definitively determine if Ser365Cys is a disease-causing mutation or a rare benign variant. The variant is found in DCM-CRDM panel(s).
