The p.Leu537fs variant in NEXN has not been previously reported in individuals with cardiomyopa thy, but has been identified in 1/66208 European chromosomes by the Exome Aggreg ation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs779350415). This variant is predicted to cause a frameshift, which alters the protein?s amino ac id sequence beginning at position 537 and leads to a premature termination codon 7 amino acids downstream. Although the severe nature of this change increases t he likelihood that the variant is pathogenic, the NEXN gene has not been widely studied and the spectrum of variants leading to disease is not well-defined. Los s of NEXN function has been shown to cause DCM in zebrafish; however, it remains unclear if one or both copies of the gene need to be affected to cause disease (Hassel 2009, Wang 2010). In summary, while there is some suspicion for a pathog enic role, the clinical significance of the p.Leu537fs variant is uncertain.
