Variant summary
Our verdict is Pathogenic. Variant got 15 ACMG points: 15P and 0B. PM1PM2PM5PP3PP5_Very_Strong
The NM_000454.5(SOD1):c.301G>A(p.Glu101Lys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. E101G) has been classified as Pathogenic.

Amyotrophic lateral sclerosis type 1 Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jan 18, 2024 | This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 101 of the SOD1 protein (p.Glu101Lys). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individuals with autosomal dominant amyotrophic lateral sclerosis (PMID: 15258228, 20460594, 20540686, 29411640; Invitae). It has also been observed to segregate with disease in related individuals. This variant is also known as 382G>A (E100K). ClinVar contains an entry for this variant (Variation ID: 574319). 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 not expected to disrupt SOD1 protein function with a negative predictive value of 95%. Experimental studies have shown that this missense change affects SOD1 function (PMID: 19483195, 23280792, 25600987). This variant disrupts the p.Glu101 amino acid residue in SOD1. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 19483195, 20399791, 23280792, 26362407, 28105640). 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. - |
not provided Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Athena Diagnostics | Jun 07, 2021 | This variant has not been reported in large, multi-ethnic general populations (http://gnomad.broadinstitute.org). This variant has been identified in multiple unrelated individuals with clinical features associated with this gene. In some published literature, this variant is referred to as E100K. Assessment of experimental evidence suggests this variant results in abnormal protein function. This variant increased propensity of the protein to form aggregates (PMID: 19483195, 25600987). - |
