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 frequency of this variant in the general population is consistent with pathogenicity. (Genome Aggregation Database (gnomAD), Cambridge, MA (URL: http://gnomad.broadinstitute.org)) This variant has been identified in multiple unrelated individuals with sporadic or familial amyotrophic lateral sclerosis, and has been reported to exhibit reduced penetrance in at least one family. At least one other missense variant at this codon is considered to be pathogenic or likely pathogenic. Assessment of experimental evidence suggests this variant results in abnormal protein function.

The FUS c.1561C>T variant is predicted to result in the amino acid substitution p.Arg521Cys. This variant has been reported to be causative for amyotrophic lateral sclerosis (ALS, Kwiatkowski et al. 2009. PubMed ID: 19251627; Vance et al. 2009. PubMed ID: 19251628; Blair et al. 2010. PubMed ID: 19965854; Yamamoto-Watanabe et al. 2010. PubMed ID: 20621307). This variant is reported in 0.0041% of alleles in individuals of African descent in gnomAD. This variant is interpreted as pathogenic. -

This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 521 of the FUS protein (p.Arg521Cys). This variant is present in population databases (rs121909668, gnomAD 0.004%). This missense change has been observed in individual(s) with amyotrophic lateral sclerosis (PMID: 19251627, 19251628, 20598774, 20621307; Invitae). In at least one individual the variant was observed to be de novo. It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 16224). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. Experimental studies have shown that this missense change affects FUS function (PMID: 19251628, 21487023). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. This variant disrupts the p.Arg521 amino acid residue in FUS. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 19251627, 20577002, 20668259, 22055719; Invitae). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic. -
