Variant summary

Our verdict is Pathogenic. The variant received 10 ACMG points: 10P and 0B. PM1PM5PP2PP3_StrongPP5

The NM_000454.5(SOD1):c.289G>A(p.Asp97Asn) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000109 in 1,461,806 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 14/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D97V) has been classified as Likely pathogenic.

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]

ACMG classification

Classification was made for transcript

Our verdict: Pathogenic. The variant received 10 ACMG points.

PM1

In a hotspot region, there are 14 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 5 uncertain in NM_000454.5

PM5

Other missense variant is known to change same aminoacid residue: Variant chr21-31667308-A-T is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 692200.Status of the report is criteria_provided_single_submitter, 1 stars.

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 96 curated pathogenic missense variants (we use a threshold of 10). The gene has 0 curated benign missense variants. Gene score misZ: 0.83817 (below the threshold of 3.09). Trascript score misZ: 1.2198 (below the threshold of 3.09). GenCC associations: The gene is linked to amyotrophic lateral sclerosis type 1, amyotrophic lateral sclerosis, spastic tetraplegia and axial hypotonia, progressive.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.955

PP5

Variant 21-31667307-G-A is Pathogenic according to our data. Variant chr21-31667307-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 14783.
