Genes affected

FUS (HGNC:4010): (FUS RNA binding protein) This gene encodes a multifunctional protein component of the heterogeneous nuclear ribonucleoprotein (hnRNP) complex. The hnRNP complex is involved in pre-mRNA splicing and the export of fully processed mRNA to the cytoplasm. This protein belongs to the FET family of RNA-binding proteins which have been implicated in cellular processes that include regulation of gene expression, maintenance of genomic integrity and mRNA/microRNA processing. Alternative splicing results in multiple transcript variants. Defects in this gene result in amyotrophic lateral sclerosis type 6. [provided by RefSeq, Sep 2009]

The c.661_663delAGT variant in the FUS gene has been reported previously in an individual with amyotrophic lateral sclerosis, however, family segregation studies were not completed (Lattante et al., 2012). The c.661_663delAGT variant is observed in 5/23170 (0.02%) alleles from individuals of African background and 12/264602 total alleles in large population cohorts (Lek et al., 2016). The c.661_663delAGT variant causes an in-frame 3 base pair deletion, causing the loss of one Serine residue at position 221 in the protein, denoted p.Ser221del. In-silico analyses, including protein predictors and evolutionary conservation, support that this variant does not alter protein structure/function. We interpret c.661_663delAGT as a variant of uncertain significance. -

This variant, c.661_663del, results in the deletion of 1 amino acid(s) of the FUS protein (p.Ser221del), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (rs746633090, gnomAD 0.02%). This variant has been observed in individual(s) with amyotrophic lateral sclerosis (PMID: 22722621; Invitae). ClinVar contains an entry for this variant (Variation ID: 503718). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. 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. -

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
