According to what has been observed in the patients of this study and in others reported previously [5, 6], SLC39A8-CDG should be considered among CDG presenting with major hyperkinetic movement disorders such as global and segmental dystonia and dyskinesia, particularly at the orofacial region, accompanied by dysphagia [11]. The gene discussed is SLC39A8; the disease is congenital disorder of glycosylation.
