Herein, we systematically analyzed the pallidal neurons of 31 patients with inherited dystonia (Table 1), encompassing nine dystonia genes (AOPEP, KMT2B, GNAL, PANK2, PLA2G6, SGCE, THAP1, TOR1A, and VPS16),2, 24, 25 from MERs performed during the GPi‐DBS surgery. This evidence concerns the gene KMT2B and Dystonia.
