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 p.P701T variant (also known as c.2101C>A), located in coding exon 21 of the NEBL gene, results from a C to A substitution at nucleotide position 2101. The proline at codon 701 is replaced by threonine, an amino acid with highly 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. -

p.Pro701Thr (CCA>ACA): c.2101 C>A in exon 21 of the NEBL gene (NM_006393.2). The P701T variant has not been published as a mutation, nor has it been reported as a benign polymorphism to our knowledge. The P701T variant was not observed with any significant frequency in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project. The P701T variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. This substitution occurs at a position that is class-conserved within mammals. However, in silico analysis predicts this variant likely does not alter the protein structure/function. Additionally, missense mutations in nearby residues have not been reported, indicating this region of the protein may tolerate change. Therefore, based on the currently available information, it is unclear whether this variant is a pathogenic mutation or a rare benign variant. The variant is found in CARDIOMYOPATHY panel(s). -

This sequence change replaces proline, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 701 of the NEBL protein (p.Pro701Thr). This variant is present in population databases (rs371551337, gnomAD 0.07%), and has an allele count higher than expected for a pathogenic variant. 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: 201909). 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. -
