The TOR1A and THAP1 genes were screened for mutations in a cohort of 21 Brazilian patients with Primary torsion dystonia (PTD). We identified a de novo delGAG mutation in the TOR1A gene in a patient with a typical DYT1 phenotype and a novel c.1A > G (p.Met1?) mutation in THAP1 in a patient with early onset generalized dystonia with speech involvement. Mutations in these two known PTD genes, TOR1A and THAP1 , are responsible for about 10% of the PTD cases in our Brazilian cohort suggesting genetic heterogeneity and supporting the role of other genes in PTD. © 2010 Movement Disorder Society
