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	Jun 06, 2023	The c.599G>C (p.G200A) alteration is located in exon 7 (coding exon 7) of the NEBL gene. This alteration results from a G to C substitution at nucleotide position 599, causing the glycine (G) at amino acid position 200 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, 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	Nov 25, 2014	The p.Gly200Ala variant in NEBL has been identified by our laboratory in 1 child with infantile-onset DCM and segregated with disease in 2 affected relatives. It has also been identified in 1/67606 European chromosomes by the Exome Aggrega tion Consortium (ExAC, http://exac.broadinstitute.org). Computational prediction tools and conservation analysis do not provide strong support for or against an impact to the protein. In summary, the clinical significance of the p.Gly200Ala variant is uncertain. -

Feb 16, 2023

This variant is present in population databases (rs727503336, gnomAD 0.02%). 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: 164763). 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. This sequence change replaces glycine, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 200 of the NEBL protein (p.Gly200Ala). -
