Abstract

Recently, association of a TOR1A(DYT1)/TOR1B risk haplotype with common forms of idiopathic dystonia has been reported in the Icelandic population. Here we report a strong association of two single nucleotide polymorphisms within or in close proximity to the TOR1A 3'UTR, with the lowest p value being 0.000008, in a larger cohort of German and Austrian patients with predominantly focal sporadic dystonia.
