A variant of uncertain significance has been identified in the NEXN gene. The c.1820_1822delGAG variant has not been published as pathogenic or been reported as benign to our knowledge. The c.1820_1822delGAG variant is not observed at a significant frequency in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). The c.1820_1822delGAG variant results in an in-frame deletion of a Glycine residue at codon 607, denoted p.Gly607del, and does not result in a shift in the reading frame or a premature stop codon. No nearby in-frame deletions in the NEXN gene have been reported in the Human Gene Mutation Database (HGMD) in association with cardiomyopathy, and the majority of variants in the NEXN gene reported in HGMD are missense variants (Stenson et al., 2014). However, in silico analysis predicts this variant is probably damaging to the protein structure/function. Therefore, based on the currently available information, it is unclear whether this variant is pathogenic or rare benign.
