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

Collection Method:clinical testing

The Gln228Glu variant in NEBL has not been previously reported in individuals wi th cardiomyopathy, but has been identified in 0.1% (5/4406) of African American chromosomes by the NHLBI Exome Sequencing Project (http://evs.gs.washington.edu/ EVS/; dbSNP rs143644290). Computational prediction tools and conservation analys is do not provide strong support for or against an impact to the protein. Additi onal information is needed to fully assess the clinical significance of the Gln2 28Glu variant. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.682C>G (p.Q228E) alteration is located in exon 7 (coding exon 7) of the NEBL gene. This alteration results from a C to G substitution at nucleotide position 682, causing the glutamine (Q) at amino acid position 228 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
