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 Tyr402Ser variant in NEBL has not been reported in the literature but has be en identified in a Caucasian infant with DCM tested by our laboratory (LMM unpub lished data). This variant has been identified in 1/8600 European American chrom osomes from a broad population by the NHLBI Exome Sequencing Project (http://evs .gs.washington.edu/EVS/). The affected amino acid is not well conserved in evolu tion, suggesting that this change may be tolerated. This is also supported by co mputational predictions (AlignGVGD, PolyPhen2, and SIFT), though this informatio n is not predictive enough to rule out pathogenicity. Additional information is needed to fully assess the clinical significance of the Tyr402Ser variant. -

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 (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. ClinVar contains an entry for this variant (Variation ID: 45477). This variant has not been reported in the literature in individuals affected with NEBL-related conditions. This variant is present in population databases (rs375569591, gnomAD 0.01%). This sequence change replaces tyrosine, which is neutral and polar, with serine, which is neutral and polar, at codon 402 of the NEBL protein (p.Tyr402Ser). -
