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]
RIF1 (HGNC:23207): (replication timing regulatory factor 1) This gene encodes a protein that shares homology with the yeast teleomere binding protein, Rap1 interacting factor 1. This protein localizes to aberrant telomeres may be involved in DNA repair. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Apr 2010]

This is a RefSeq error. The reference base (c.24538G) is the minor allele. This allele (G) has been identified in 36% (2917/8198) of European American chromosom es and 40% (1501/3704) of African American chromosomes by the NHLBI Exome Sequen cing Project (http://evs.gs.washington.edu/EVS/; dbSNP rs7575451) and thus meets criteria to be classified as benign. -

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -

Significance: Benign
Review Status: criteria provided, single submitter
Collection Method: clinical testing

Variant summary: The NEB c.24538G>C (p.Ala8180Pro) variant involves the alteration of a conserved nucleotide, which 3/4 in silico tools (query not functioning for SNPs&Go) predict a "benign" outcome. The variant of interest was observed in the large, broad control population, ExAC, with an allele frequency of 0.6499357 (74779/115056 (24235 homozygotes)). Therefore, suggesting that the C allele is the major allele observed in the general population. In addition, multiple clinical diagnostic laboratories classify the variant as Benign. Therefore, the variant of interest has been classified as Benign. -
