GeneDx RCV000183650 SCV000236119 uncertain significance not provided 2013-01-11 criteria provided, single submitter clinical testing p.Glu148Lys (GAA>AAA): c.442 G>A in exon 5 of the NEXN gene (NM_144573.3). The Glu148Lys variant in the NEXN gene has not been reported as a disease-causing mutation or as a benign polymorphism to our knowledge. Glu148Lys results in a non-conservative amino acid substitution of a negatively charged Glutamic acid with a positively charged Lysine at a position that is not highly conserved. The Glu148Lys variant was not observed in approximately 6,000 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, only very few NEXN mutations have been reported in association with cardiomyopathy to date, and none of those were located nearby. The variant is found in DCM panel(s).
