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]

Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

The c.2485G>A (p.V829M) alteration is located in exon 24 (coding exon 24) of the NEBL gene. This alteration results from a G to A substitution at nucleotide position 2485, causing the valine (V) at amino acid position 829 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

Variant classified as Uncertain Significance - Favor Benign. The Val829Met varia nt in NEBL has not been previously reported in individuals with cardiomyopathy o r in large population studies. Computational prediction tools and conservation analysis do not provide strong support for or against an impact to the protein, though 2 fish species carry a methionine (Met) at this position, raising the pos sibility that this change may be tolerated. Additional information is needed to fully assess the clinical significance of the Val829Met variant. -

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 methionine, which is neutral and non-polar, at codon 829 of the NEBL protein (p.Val829Met). This variant is present in population databases (rs727504979, 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: 179598). 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 disruptive. 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. -
