Submissions by phenotype
not provided Pathogenic:2
This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 38 of the ANXA11 protein (p.Gly38Arg). This variant is present in population databases (rs142083484, gnomAD 0.008%). This missense change has been observed in individuals with amyotrophic lateral sclerosis (PMID: 28469040, 29650794, 33087501, 33218681; internal data). ClinVar contains an entry for this variant (Variation ID: 488354). Algorithms developed to predict the effect of variants on gene product structure and function are not available or were not evaluated for this variant. Experimental studies have shown that this missense change affects ANXA11 function (PMID: 28469040, 30109997, 33087501). For these reasons, this variant has been classified as Pathogenic. -

ANXA11-related disorder Pathogenic:1
The ANXA11 c.112G>A variant is predicted to result in the amino acid substitution p.Gly38Arg. This variant has been reported to be causative for amyotrophic lateral sclerosis (ALS, Smith et al. 2017. PubMed ID: 28469040; Müller et al. 2018. PubMed ID: 29650794; Teyssou et al. 2020. PubMed ID: 33218681). In vitro functional studies have shown the p.Gly38Arg variant leads to stress granule formation, and this supports its pathogenicity in ALS (Nahm et al. 2020. PubMed ID: 33087501). This variant is reported in 0.0077% of alleles in individuals of European (Non-Finnish) descent in gnomAD. This variant is interpreted as pathogenic. -
Amyotrophic lateral sclerosis Pathogenic:1
PM2_supporting: the highest population allele frequency in gnomAD v4.0 is 0.00007705 (0.008%; 8/103830 alleles in European non-Finnish population) and in gnomAD v3.1.2 is 0.0004798 (0.048%; 1/2084 alleles in Other population) and the variant is absent from an internal database of 1412 alleles. PP3 met- multiple lines of computational evidence support a deleterious effect on the gene or gene product. PM1 met- variant is located in the N-terminal low complexity domain of ANXA11 near the calcyclin binding region and clusters with other pathogenic variants (p.P35A, p.P36R, p.D40G/p.D40Y). PS3_supporting- various functional studies provide evidence that this variant affects protein function (PMID 33087501, 30109997, 28469040). PS4_moderate- variant identified in 7 unrelated probands with consistent phenotype for disorder (PMID 35047667, 33218681, 33087501, 29650794, 28469040, clinical testing). -
