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=0.013075799).
BP6
Variant 2-151633887-T-A is Benign according to our data. Variant chr2-151633887-T-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 450097.
BS1
Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00149 (227/152292) while in subpopulation AFR AF = 0.0052 (216/41562). AF 95% confidence interval is 0.00463. There are 1 homozygotes in GnomAd4. There are 121 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
