Genes affected

NEB (HGNC:7720): (nebulin) This gene encodes nebulin, a giant protein component of the cytoskeletal matrix that coexists with the thick and thin filaments within the sarcomeres of skeletal muscle. In most vertebrates, nebulin accounts for 3 to 4% of the total myofibrillar protein. The encoded protein contains approximately 30-amino acid long modules that can be classified into 7 types and other repeated modules. Protein isoform sizes vary from 600 to 800 kD due to alternative splicing that is tissue-, species-,and developmental stage-specific. Of the 183 exons in the nebulin gene, at least 43 are alternatively spliced, although exons 143 and 144 are not found in the same transcript. Of the several thousand transcript variants predicted for nebulin, the RefSeq Project has decided to create three representative RefSeq records. Mutations in this gene are associated with recessive nemaline myopathy. [provided by RefSeq, Sep 2009]

Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

NEB exons 82-105 are organized in three repetitive blocks of 8 exons each and be cause these blocks are nearly identical in sequence, homologous exons (e.g., exo ns 86, 94, and 102) are co-amplified and sequenced (each amplicon consists of 6 alleles). This variant represents a nonhomologous position within the three repe titive blocks (c.13105C, c.14563T, and c.16021T) and is categorized as "Likely B enign" as all three positions code for an Leucine (p.Leu4369, p.Leu4855, p.Leu53 41). -
