2021; Reinhold et al. 2024). Supporting repetitive movement as a “second hit,” overtrained actions can lead to focal dystonias like musician's dystonia and writer's cramp (Byl et al. 1996; Furuya and Hanakawa 2016; Altenmüller and Jabusch 2010). While torsinA mutations are most associated with generalized early‐onset dystonia, they are also rarely observed in patients with adult‐onset focal dystonia (Gasser et al. 1998; Grundmann et al. 2003; Magrinelli et al. 2018; Opal et al. 2002). The gene discussed is TOR1A; the disease is Dystonia.
