THAP1 encodes a transcription factor but its regulation is largely elusive. TOR1A was shown to be repressed by THAP1 in vitro. Notably, mutations in both of these genes lead to dystonia (DYT6 or DYT1).
View Article and Find Full Text PDFA three-nucleotide (GAG) deletion (ΔE) in TorsinA (TOR1A) has been identified as the most common cause of dominantly inherited early-onset torsion dystonia (DYT1). TOR1A encodes a chaperone-like AAA+-protein localized in the endoplasmic reticulum. Currently, only three additional, likely mutations have been reported in single dystonia patients.

To further evaluate the mutational spectrum of THAP1 and its associated phenotype, we sequenced THAP1 in 567 patients with focal (n = 461), segmental (n = 68), or generalized dystonia (n = 38).

This revealed 2 candidate regions including the THAP1 gene, where heterozygous mutations cause dystonia 6. A homozygous missense mutation in THAP1 (c.
View Article and Find Full Text PDFMutations in THAP1 have been associated with dystonia 6. THAP1 encodes a transcription factor with mostly unknown targets. We tested the hypothesis that THAP1 regulates the expression of DYT1 (TOR1A), another dystonia-causing gene.
