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]

Hypertrophic cardiomyopathy;C0018790:Cardiac arrest

Uncertain:1

Oct 15, 2018

Agnes Ginges Centre for Molecular Cardiology, Centenary Institute

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:research

NEBL Arg179Ter has been previously reported in heterozygous form in a patient presenting with fatigue, attributed to atrial flutter, left bundle branch block, enlarged LV and reduced ejection fraction (Arbustini et al., 2018), and homozygous form in an infant with pulmonary hypertension and LV dysfunction (Scott et al., 2018). We identified this heterozygous variant in 2 probands of Maori descent; 1 with HCM and 1 out of hospital cardiac arrest. NEBL Arg179Ter is present in the Genome Aggregation Database (MAF= 0.000022, http://gnomad.broadinstitute.org/), however Oceanian/Polynesian ethnicity's are not well represented. As a result we classify NEBL Arg179Ter as a variant of 'uncertain significance'. -

Primary dilated cardiomyopathy

Uncertain:1

Jan 17, 2025

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.Arg179*) 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 (rs370153729, gnomAD 0.01%). 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: 569179). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. 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. -

Hypertrophic cardiomyopathy

Victorian Clinical Genetics Services, Murdoch Childrens Research Institute

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 (v3) <0.001 for a dominant condition (11 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 -
