Molecular basis of DYT1 and DYT6 primary dystonia in Indian patients

Background Dystonia is the third most common movement disorder. It is manifested by involuntary and sustained muscle contractions with frequent twists and repetitive movement, abnormal posture and functional impairment. Genetic factors play significant role for causing dystonia. Till date twenty five loci (DYT1-DYT25) and sixteen genes have been reported for dystonia. The present study reports the screening of TOR1A (DYT 1) and THAP1 (DYT 6) among primary torsion dystonia patients of India.
