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 Val5Ala variant in NEBL has been identified in 1/4406 African American chrom osomes from a broad population by the NHLBI Exome Sequencing Project (http://evs .gs.washington.edu/EVS; dbSNP rs145770601), though this could represent a presym ptomatic individual. Computational analyses (biochemical amino acid properties, conservation, AlignGVGD, and PolyPhen2) suggest that the variant may not impact the protein, though this information is not predictive enough to rule out pathog enicity. Additional information is needed to fully assess the variant's clinical significance. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces valine, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 5 of the NEBL protein (p.Val5Ala). This variant is present in population databases (rs145770601, gnomAD 0.07%), and has an allele count higher than expected for a pathogenic variant. This missense change has been observed in individual(s) with dilated cardiomyopathy (PMID: 32746448). ClinVar contains an entry for this variant (Variation ID: 45481). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬†is likely to be tolerated. 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. -
