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]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -9 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.053400576).

BP6

Variant 2-151672608-T-C is Benign according to our data. Variant chr2-151672608-T-C is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 534085.

BS1

Variant frequency is greater than expected in population sas. GnomAdExome4 allele frequency = 0.000164 (239/1461692) while in subpopulation SAS AF = 0.00264 (228/86258). AF 95% confidence interval is 0.00236. There are 1 homozygotes in GnomAdExome4. There are 180 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check.

The c.4060A>G (p.K1354E) alteration is located in exon 37 (coding exon 35) of the NEB gene. This alteration results from a A to G substitution at nucleotide position 4060, causing the lysine (K) at amino acid position 1354 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
