Suspecting atypical Parkinsonism, a Wilson disease study and genetic tests of Charcot–Marie–Tooth (CMT), atypical Parkinsonisms (PARKs, GAB, DNAJC6, VPS13C, PINK, and LG), and atypical spinal–muscular atrophies (DYNC1H1, BICD, VAPB, GARS, DYNC1H1, mtATP6, and mtATP8) were carried out. The gene discussed is DYNC1H1; the disease is Wilson disease.
