Additionally, autoantibodies associated with central nervous system demyelination (AQP4, MOG, MBP), encephalomyelitis/encephalitis (IgLON5, DPPX, DRD2, mGluR5, mGluR1, neurexin-3α, NMDA, AMPA1, AMPA2, LGI1, GABAb, CASPR2), and gangliosides (GM1, GM2, GM3, GM4, GD1a, GD1b, GD2, GD3, GQ1b, GT1a, GT1b, sulfatide) were undetectable in both blood and CSF, even on two separate occasions. The gene discussed is DRD2; the disease is encephalomyelitis.
