PMID: 27992417 reports variants in 27 individuals with early onset dystonia. In 20 patients this was de novo, and in a further 3 cases was maternally inherited (with one mother with mild symptoms), suggesting possible incomplete penetrance in two cases. Microdeletions and variants predicted to cause protein truncating, splice defects or nonsense-mediated mRNA, and nonsynonymous missense variants are reported. In silico prediction and expression analysis were also carried out to support the findings.

Added the 'treatable' tag: the publication reports that bilateral globus pallidus interna deep brain stimulation (GPi-DBS) led to clinical benefit in patients with dystonia with KMT2B variants.
