Genes affected

NEBL (HGNC:16932): (nebulette) This gene encodes a nebulin like protein that is abundantly expressed in cardiac muscle. The encoded protein binds actin and interacts with thin filaments and Z-line associated proteins in striated muscle. This protein may be involved in cardiac myofibril assembly. A shorter isoform of this protein termed LIM nebulette is expressed in non-muscle cells and may function as a component of focal adhesion complexes. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Mar 2010]

Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The Arg613X variant in NEBL has not been previously reported in individuals with cardiomyopathy, but has been identified in 4/8600 European American chromosomes by the NHLBI Exome Sequencing Project (http://evs.gs.washington.edu/EVS/; dbSNP rs146471913). This nonsense variant leads to a premature termination codon at p osition 613, which is predicted to lead to a truncated or absent protein. Missen se variants in NEBL have been reported in individuals with DCM and endocardial f ibroelastosis, and mouse studies provide support for a role of this gene in the etiology of dilated cardiomyopathy (Purevjav 2010), but the spectrum of variants for this gene has not been fully elucidated. In summary, additional studies are needed to fully assess the clinical significance of this variant. -

Nonsense variant predicted to result in protein truncation or nonsense mediated decay in a gene for which loss-of-function is not an established mechanism of disease; Has not been previously published as pathogenic or benign to our knowledge; Variants in candidate genes are classified as variants of uncertain significance in accordance with ACMG guidelines (PMID: 25741868); This variant is associated with the following publications: (PMID: 25741868) -

Primary dilated cardiomyopathy

Labcorp Genetics (formerly Invitae), Labcorp

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change creates a premature translational stop signal (p.Arg613*) in the NEBL gene. It is expected to result in an absent or disrupted protein product. However, the current clinical and genetic evidence is not sufficient to establish whether loss-of-function variants in NEBL cause disease. This variant is present in population databases (rs146471913, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with NEBL-related conditions. ClinVar contains an entry for this variant (Variation ID: 178096). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as VUS-3B. Following criteria are met: 0105 - The mechanism of disease for this gene is not clearly established. However, loss of function is an unlikely mechanism of disease, as null mouse models have normal cardiac function (PMID: 25987543). (I) 0107 - This gene is associated with autosomal dominant disease. (I) 0201 - Variant is predicted to cause nonsense-mediated decay (NMD) and loss of protein (premature termination codon is located at least 54 nucleotides upstream of the final exon-exon junction). (SP) 0251 - This variant is heterozygous. (I) 0302 - Variant is present in gnomAD (v2) <0.001 for a dominant condition (44 heterozygotes, 0 homozygotes). (SP) 0710 - Other NMD predicted variants comparable to the one identified in this case have inconclusive previous evidence for pathogenicity. Other variants predicted to cause NMD have been reported as VUS in ClinVar. (I) 0809 - Previous evidence of pathogenicity for this variant is inconclusive. This variant has been reported as a VUS in ClinVar. (I) 0905 - No published segregation evidence has been identified for this variant. (I) 1007 - No published functional evidence has been identified for this variant. (I) 1208 - Inheritance information for this variant is not currently available in this individual. (I) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign -
