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]

not provided Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingGeneDxSep 11, 2024Has not been previously published as pathogenic or benign to our knowledge; In silico analysis supports a deleterious effect on splicing; Variants in candidate genes are classified as variants of uncertain significance in accordance with ACMG guidelines (PMID: 25741868) -
Primary dilated cardiomyopathy Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJan 20, 2025This sequence change falls in intron 12 of the NEBL gene. It does not directly change the encoded amino acid sequence of the NEBL protein. It affects a nucleotide within the consensus splice site. This variant is present in population databases (rs370026081, gnomAD 0.02%). 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: 423353). Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. 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. -
