Variant summary
Our verdict is Pathogenic. Variant got 14 ACMG points: 14P and 0B. PM1PM2PM5PP5_Very_Strong
The NM_004960.4(FUS):c.1562G>A(p.Arg521His) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. Variant has been reported in ClinVar as Pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R521C) has been classified as Pathogenic.

Amyotrophic lateral sclerosis type 6 Pathogenic:2
The missense variant p.R521H in FUS (NM_004960.4) has been previously reported in affected families (Kwiatkowski, T et al, Vance, C et al). It has been classified as Pathogenic in the ClinVar database. Another substitution affecting the same aminoacid R251C has been reported in multiple families with ALS, based on which the residue can be considered as significant. Functional studies have shown a damaging effect (Vance C et al, 2013). The missense variant c.1562G>A (p.R521H) in FUS (NM_004960.4) is observed in 1/113646 (0.0009%) alleles from individuals of European (Non-Finnish) background in the gnomAD dataset (Exome Aggregation Consortium et al., 2016), but was not seen in the homozygous state. The p.R521H missense variant is predicted to be damaging by both SIFT and PolyPhen2. The nucleotide c.1562 in FUS is predicted conserved by GERP++ and PhyloP across 100 vertebrates. For these reasons, this variant has been classified as Pathogenic. -

Amyotrophic lateral sclerosis type 6;C3539195:Tremor, hereditary essential, 4 Pathogenic:1
This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 521 of the FUS protein (p.Arg521His). This variant is present in population databases (rs121909671, gnomAD 0.0009%). This missense change has been observed in individuals with amyotrophic lateral sclerosis (PMID: 19251627, 22340366, 23217123, 27604643, 28430856). ClinVar contains an entry for this variant (Variation ID: 16225). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). 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, 19251628, 20577002, 20621307, 22055719, 22340366, 26500017; 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. -
