Laboratory for Molecular Medicine, Partners HealthCare Personalized Medicine RCV000041167 SCV000064858 uncertain significance not specified 2015-04-08 criteria provided, single submitter clinical testing The p.Ser596Arg variant in NEXN has been identified by our laboratory in 1 Cauca sian infant with DCM. This variant has also been identified in 28/66528 European chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitu te.org; dbSNP rs199738750). Computational prediction tools and conservation anal ysis do not provide strong support for or against an impact to the protein. In s ummary, the clinical significance of the p.Ser596Arg variant is uncertain.
Invitae RCV000232351 SCV000291368 uncertain significance Dilated cardiomyopathy 1CC; Familial hypertrophic cardiomyopathy 20 2018-08-27 criteria provided, single submitter clinical testing This sequence change replaces serine with arginine at codon 596 of the NEXN protein (p.Ser596Arg). The serine residue is moderately conserved and there is a moderate physicochemical difference between serine and arginine. This variant is present in population databases (rs199738750, ExAC 0.04%). This variant has not been reported in the literature in individuals with a NEXN-related disease. ClinVar contains an entry for this variant (Variation ID: 47897). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. In summary, this variant has uncertain impact on NEXN function. The available evidence is currently insufficient to determine its role in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
