Genes affected
SOD1 (HGNC:11179): (superoxide dismutase 1) The protein encoded by this gene binds copper and zinc ions and is one of two isozymes responsible for destroying free superoxide radicals in the body. The encoded isozyme is a soluble cytoplasmic protein, acting as a homodimer to convert naturally-occuring but harmful superoxide radicals to molecular oxygen and hydrogen peroxide. The other isozyme is a mitochondrial protein. In addition, this protein contains an antimicrobial peptide that displays antibacterial, antifungal, and anti-MRSA activity against E. coli, E. faecalis, S. aureus, S. aureus MRSA LPV+, S. agalactiae, and yeast C. krusei. Mutations in this gene have been implicated as causes of familial amyotrophic lateral sclerosis. Rare transcript variants have been reported for this gene. [provided by RefSeq, Jul 2020]

Pathogenic, criteria provided, single submitter | clinical testing | 3billion | - | The variant is not observed in the gnomAD v2.1.1 dataset. The variant is located in a mutational hot spot and/or well-established functional domain in which established pathogenic variants have been reported. Missense changes are a common disease-causing mechanism. In silico tool predictions suggest damaging effect of the variant on gene or gene product (REVEL: 0.85; 3Cnet: 0.97). Same nucleotide change resulting in same amino acid change has been previously reported as pathogenic/likely pathogenic with strong evidence (ClinVar ID: VCV000468253 / PMID: 9556377). Different missense changes at the same codon (p.Asn87Asp, p.Asn87Lys) have been reported to be associated with SOD1 -related disorder (PMID: 17299743, 20309572). Therefore, this variant is classified as Pathogenic according to the recommendation of ACMG/AMP guideline. - |

Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jul 10, 2023 | This missense change has been observed in individuals with autosomal recessive juvenile-onset amyotrophic lateral sclerosis (ALS) and autosomal dominant ALS (PMID: 8971099, 9556377, 20577002, 22244934, 26601740, 26622980, 27604643). ClinVar contains an entry for this variant (Variation ID: 468253). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt SOD1 protein function. For these reasons, this variant has been classified as Pathogenic. This sequence change replaces asparagine, which is neutral and polar, with serine, which is neutral and polar, at codon 87 of the SOD1 protein (p.Asn87Ser). This variant is not present in population databases (gnomAD no frequency). - |
