Summaries for Dystonia 6, Torsion

UniProtKB/Swiss-Prot : 71 Dystonia 6, torsion: A primary torsion dystonia. Dystonia is defined by the presence of sustained involuntary muscle contractions, often leading to abnormal postures. Dystonia type 6 is characterized by onset in early adulthood, cranial or cervical involvement in about half of the cases, and frequent progression to involve multiple body regions.

MalaCards based summary : Dystonia 6, Torsion, also known as dyt6, is related to adolescent-onset dystonia of mixed type and dystonia, and has symptoms including myoclonus, dysarthria and torticollis. An important gene associated with Dystonia 6, Torsion is THAP1 (THAP Domain Containing 1). Affiliated tissues include brain and tongue.

OMIM : 54
Dystonia-6 is an autosomal dominant movement disorder characterized by early involvement of craniofacial muscles with secondary generalization often involving the arms, and laryngeal dystonia that causes speech difficulties (review by Djarmati et al., 2009). Blanchard et al. (2011) provided a review of dystonia-6 and the THAP1 gene. (602629)

Disease Ontology : 12 A characterized by autosomal dominant inheritance of early-onset generalised dystonia typically involing the craniocervical region with spasmodic dysphonia that has material basis in heterozygous mutation in the THAP1 gene on chromosome 8p11.
