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 2346+6G>A variant in NEBL has not been previously reported in individuals wi th cardiomyopathy, but has been identified in 1/128 Mexican chromosomes by the 1 000 Genomes Project (dbSNP rs201822024). This variant is located in the 5' splic e region. Computational tools do not suggest an impact to splicing, though this information is not predictive enough to rule out pathogenicity. Additional infor mation is needed to fully assess the clinical significance of this variant. -

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

This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -
