CNTNAP2 and Chorea: Therefore, here we discussed how characteristic phenotypes (like FBDS with LGI1-antibodies, or leg myoclonus affecting stance and gait with CASPR2-antibodies) or associated features (combined syndromes, e.g. chorea with neuropathy in paraneoplastic chorea with Hu- or CRMP5-antibodies) will suggest an autoimmune movement disorder.
