Description

The SOD1 c.272A>C variant is predicted to result in the amino acid substitution p.Asp91Ala. The c.272A>C change, previously described as p.Asp90Ala using legacy nomenclature, is a known founder variant found within the Scandinavian population and has previously been reported in autosomal recessive amyotrophic lateral sclerosis (ALS, Andersen et al. 1995. PubMed ID: 7647793; Gellera et al. 2001. PubMed ID: 11369193; Hand et al. 2001. PubMed ID: 11220750; Felbecker et al. 2010. PubMed ID: 20460594). In general, individuals who are homozygous for the c.272A>C variant present with longer duration of disease compared to autosomal dominant SOD1 mediated ALS (Tripolszki et al. 2017. PubMed ID: 28222900; Luisa Conforti et al. 2009. PubMed ID: 18608106). Heterozygous individuals have been reported in a few cases with some individuals presenting with atypical ALS (Origone et al. 2009. PubMed ID: 19922148; Dalla Bella et al. 2014. PubMed ID: 24591457; Khoris et al. 2000. PubMed ID: 10809943). This variant is reported in 1.2% of alleles in individuals of European (Finnish) descent in gnomAD; however, in the general population, its allele frequency is approximately 0.074%. This variant is interpreted as likely pathogenic.
