Abnormalities of motor function, transcription and cerebellar structure in mouse models of THAP1 dystonia.

ABSTRACT: DYT6 dystonia is caused by mutations in THAP1 [Thanatos-associated (THAP) domain-containing apoptosis-associated protein] and is autosomal dominant and partially penetrant. Like other genetic primary dystonias, DYT6 patients have no characteristic neuropathology, and mechanisms by which mutations in THAP1 cause dystonia are unknown. Thap1 is a zinc-finger transcription factor, and most pathogenic THAP1 mutations are missense and are located in the DNA-binding domain. There are also nonsense mutations, which act as the equivalent of a null allele because they result in the generation of small mRNA species that are likely rapidly degraded via nonsense-mediated decay. The function of Thap1 in neurons is unknown, but there is a unique, neuronal 50-kDa Thap1 species, and Thap1 levels are auto-r
