Of the 30 autoimmune GFAP-A patients, 10 had meningitis or meningoencephalitis, 4 had encephalomyelitis, 5 had optic neuritis, 3 had acute disseminated encephalomyelitis, and the rest had transverse myelitis, cranial neuritis, or cerebellitis (Figure 2D). This evidence concerns the gene GFAP and transverse myelitis.
