Title: Genetics of dystonia. Author: Fuchs T, Ozelius LJ. Journal: Semin Neurol; 2011 Nov; 31(5):441-8. PubMed ID: 22266882. Abstract: Dystonia is characterized by muscle contractions leading to abnormal postures with involuntary twisting and repetitive movements. Inherited dystonia designated by DYT locus symbols can be separated into three broad phenotypic categories: primary torsion dystonia (PTD), where dystonia is the only clinical sign (except for tremor) (DYT1, 2, 4, 6, 7, 13, 17, and 21); dystonia plus loci, where other phenotypes in addition to dystonia, including parkinsonism or myoclonus, are present (DYT3, 5/14, 11, 12, 15, and 16); and paroxysmal forms of dystonia/dyskinesia (DYT8, 9, 10, 18, 19, and 20). Currently, 19 loci including 10 genes have been identified for inherited dystonias. In this review, the phenotypes associated with these loci and the responsible genes will be discussed.[Abstract] [Full Text] [Related] [New Search]
