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]

Likely benign, criteria provided, single submitter	clinical testing	Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	Sep 04, 2017	p.Ile828Val in exon 24 of NEBL: This variant is not expected to have clinical si gnificance due to a lack conservation across species, including mammals. Of note , 15 mammals have a Valine (Val) at this position despite high nearby amino acid conservation. In addition, computational prediction tools do not suggest a high likelihood of impact to the protein. It has been identified in 0.2% (234/126492 ) of European chromosomes by the Genome Aggregation Database (gnomAD, http://gno mad.broadinstitute.org; dbSNP rs143930021). -
Likely benign, criteria provided, single submitter	clinical testing	Ambry Genetics	Oct 17, 2022	This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
