The Met337Val variant in TARDBP has been reported in Western countries and Asia with autosomal dominant amyotrophic lateral sclerosis, segregated with the disease in over 10 affected relatives (Sreedharan 2008, Kirby 2010, Tamaoka 2010, Xu 2018), and was absent from large population studies. Additionally, studies indicate that the Met337Var variant transgenic mouse presented worsened dose-dependent disease phenotype in terms of motor dysfunction, neurodegeneration, gliosis, and development of ubiquitin and phosphorylated TDP-43 pathology (Janssens 2013). In summary, the Met337Val variant meets our criteria to be classified as pathogenic based upon segregation studies, absence from controls, and functional evidence.

This sequence change replaces methionine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 337 of the TARDBP protein (p.Met337Val). This variant is present in population databases (rs80356730, gnomAD 0.002%). This missense change has been observed in individual(s) with amyotrophic lateral sclerosis (ALS) (PMID: 18309045, 20154440, 28430856, 28709720). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 5228). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt TARDBP protein function with a negative predictive value of 80%. Experimental studies have shown that this missense change affects TARDBP function (PMID: 18309045, 19465477, 20600671, 23401527, 23827948, 24143176, 24507191). For these reasons, this variant has been classified as Pathogenic. (less)

This is a nonsynonymous variant in the TARDBP gene. Pathogenci variants in this gene have been associated with autosomal dominant Amyotrophic lateral sclerosis 10, with or without FTD. This variant has been reported in two unrelated individuals with amyotrophic lateral sclerosis (PMID:28430856, 28709720) (PS4) and segregated with ALS in two families (PMID: 18309045, 20154440) (PP1). This variant is absent from control populations (https://gnomad.broadinstitute.org/) (PM2). Functional studies have shown that this missense variant alters TARDBP protein function (PMID: 18309045, 19465477, 20600671, 23401527, 23827948, 24143176, 24507191) (PS3). Based on this evidence, the variant is classified as pathogenic autosomal dominant Amyotrophic lateral sclerosis 10, with or without FTD. (less)

In an English family segregating autosomal dominant amyotrophic lateral sclerosis without frontotemporal dementia (612069), Sreedharan et al. (2008) identified an A-to-G transition at nucleotide 1009 in exon 6 of the TARDBP gene, resulting in a methionine-to-valine substitution at codon 337 (M337V). Methionine at this position is invariant in human, orangutan, mouse, opossum, chicken, frog, and zebrafish. (less)
