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]

The c.2417C>T (p.T806I) alteration is located in exon 24 (coding exon 24) of the NEBL gene. This alteration results from a C to T substitution at nucleotide position 2417, causing the threonine (T) at amino acid position 806 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

The Thr806Ile variant in NEBL has not been previously reported in individuals wi th cardiomyopathy, but has been identified in 1/8600 of European American chromo somes by the NHLBI Exome Sequencing Project (http://evs.gs.washington.edu/EVS/; dbSNP rs200705273). Computational prediction tools and conservation analysis sug gest that this variant may not impact the protein, though this information is no t predictive enough to rule out pathogenicity. In summary, the clinical signific ance of the Thr806Ile variant is uncertain. -

Has not been previously published as pathogenic or benign to our knowledge; In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Variants in candidate genes are classified as variants of uncertain significance in accordance with ACMG guidelines (PMID: 25741868) -

Collection Method:clinical testing

This sequence change replaces threonine, which is neutral and polar, with isoleucine, which is neutral and non-polar, at codon 806 of the NEBL protein (p.Thr806Ile). This variant is present in population databases (rs200705273, gnomAD 0.03%). 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: 164741). 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. -
