Dystonia 32

Summary

Dystonia-32 (DYT32) is an autosomal recessive neurologic disorder characterized by sustained or intermittent muscle contractions causing abnormal movements or posturing. The onset of symptoms is in adulthood, and the disorder is slowly progressive with eventual generalized involvement of the limbs, trunk, neck, and larynx, resulting in dysarthria and dysphagia. Brain imaging may show abnormalities in the basal ganglia. There are no additional neurologic signs or symptoms (summary by Monfrini et al., 2021). In a review of the pathogenesis of disorders with prominent dystonia, Monfrini et al. (2021) classified DYT32 as belonging to a group of neurologic disorders termed 'HOPS-associated neurologic disorders' (HOPSANDs), which are caused by mutations in genes encoding various components of the autophagic/endolysosomal system, including VPS11.
