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 FUS c.52C>T variant is predicted to result in the amino acid substitution p.Pro18Ser. This variant has been reported in two unrelated individuals with amyotrophic lateral sclerosis (Belzil et al. 2011. PubMed ID: 21261515). This variant was also reported in a healthy control from a study of patients with Parkinson disease (Gao et al. 2013. PubMed ID: 24080306) and in an individual with early onset frontotemporal dementia (EOFTD), although the authors in that study did not consider it likely to strongly increase the risk of disease (Table S3, Koriath et al. 2018. PubMed ID: 30279455). This variant is reported in 0.0070% of alleles in individuals of European (non-Finnish) descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. However, the evidence from the literature, in combination with allele frequency data from public databases where available, was not sufficient to rule this variant in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -

This variant has been observed in individuals affected with frontotemporal dementia and in individuals affected with amyotrophic lateral sclerosis; however, this variant has also been observed in unaffected control individuals (PMID: 30279455, 21261515, 25631824, 24080306). 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. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant is present in population databases (rs144888138, ExAC 0.007%). This sequence change replaces proline with serine at codon 18 of the FUS protein (p.Pro18Ser). The proline residue is moderately conserved and there is a moderate physicochemical difference between proline and serine. -
