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

Variant classified as Uncertain Significance - Favor Benign. The Arg694Trp varia nt in NEBL has not been reported in the literature nor previously identified by our laboratory. This variant has been identified in 0.16% (7/4406) of African Am erican chromosomes from a broad population by the NHLBI Exome Sequencing Project (http://evs.gs.washington.edu/EVS/; dbSNP rs114875104). This frequency is too l ow to rule out a role in disease. Arginine (Arg) at position 694 is not conserve d in evolution, suggesting that a change to this position may be tolerated. This variant is less likely disease causing but additional studies are needed to ful ly assess its clinical significance. -

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

The c.2080C>T (p.R694W) alteration is located in exon 21 (coding exon 21) of the NEBL gene. This alteration results from a C to T substitution at nucleotide position 2080, causing the arginine (R) at amino acid position 694 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

NEBL NM_006393.2 exon 25 p.Arg694Trp (c.2080C>T): This variant has not been reported in the literature and is present in 0.1% (38/24960) of African alleles in the Genome Aggregation Database (http://gnomad.broadinstitute.org/variant/10-21106597-G-A). This variant is present in ClinVar (Variation ID:45491). Evolutionary conservation and computational predictive tools for this variant are unclear. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain. -

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

A variant of uncertain significance has been identified in the NEBL gene. The R694W variant has not been published as a pathogenic variant or reported as a benign variant, to our knowledge. The NHLBI Exome Sequencing Project, Exome Aggregation Consortium (ExAC) and the 1000 Genomes Project reports R694W was observed in 0.1-0.2% of individuals of African background, indicating it may be a rare (benign) variant in this population. This substitution occurs at a position that is not conserved across species. Nevertheless, the R694W 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. Finally, in silico analysis predicts this variant is probably damaging to the protein structure/function. -
