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]

Uncertain significance, criteria provided, single submitter	clinical testing	Ambry Genetics	Oct 12, 2023	The p.G894E variant (also known as c.2681G>A), located in coding exon 26 of the NEBL gene, results from a G to A substitution at nucleotide position 2681. The glycine at codon 894 is replaced by glutamic acid, an amino acid with similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
Uncertain significance, criteria provided, single submitter	clinical testing	Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	Dec 21, 2015	The p.Gly894Glu variant in NEBL has not been previously identified in individual s with cardiomyopathy and was absent from large population studies. Computationa l prediction tools and conservation analysis suggest that this variant may impac t the protein, though this information is not predictive enough to determine pat hogenicity. In summary, the clinical significance of the p.Gly894Glu variant is uncertain. -

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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 229047). This variant has not been reported in the literature in individuals affected with NEBL-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces glycine with glutamic acid at codon 894 of the NEBL protein (p.Gly894Glu). The glycine residue is highly conserved and there is a moderate physicochemical difference between glycine and glutamic acid. -
