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]

A variant of uncertain significance has been identified in the NEBL gene. The c.2 T>C variant has not been published as a pathogenic variant or been reported as a benign variant to our knowledge. This variant alters the initiator Methionine residue and the resultant protein would be described as p.Met1?" using a question mark to signify that it is not known if the loss of Met1 means that all protein translation is completely prevented or if an abnormal protein is produced using an alternate Met. The c.2 T>C variant was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. However, only four missense variants and no truncating variants in the NEBL gene have been reported in the Human Gene Mutation Database in association with disease (Stenson et al., 2014).Therefore, based on the currently available information, it is unclear whether this variant is a pathogenic variant or a rare benign variant" -

This sequence change affects the initiator methionine of the NEBL mRNA. The next in-frame methionine is located at codon 39. This variant is present in population databases (no rsID available, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with NEBL-related conditions. ClinVar contains an entry for this variant (Variation ID: 488779). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. 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. -
