We also tested some other neural autoantibodies, such as anti‐glutamate receptor antibodies (NMDA type, AMPA type 1, AMPA type 2) antibodies, anti‐LGI‐1 antibody, anti‐CASPR2 antibody, anti‐GABAB antibody, anti‐IgLON5 antibody, anti‐DPPX antibody, Anti‐GlyR1 antibody, anti‐GAD65 antibody, anti‐mGLuR5 antibody, anti‐mGluR1 antibody, anti‐Neurexin‐3α antibody, all were negative, and this was the first report of these neural autoantibodies in the CSF of patients with TS. The gene discussed is GAD2; the disease is Timothy syndrome.
