Our neural autoantibody group consisted of 14 patients with dementia and autoantibodies in their serum or CSF (serum: n = 3 recoverin, n = 2 KCNA2, n = 1 GFAP, n = IgLON5, n = 1 Zic4, n = 1 glycine, n = 1 CASPR2, n = 1 Ma2, n = 1 SOX1, n = 1 titin, n = 1 flotillin 1/2, n = 1 Yo antibodies, n = 1 neuropil antibodies, and CSF n = 1 neuropil antibodies). The gene discussed is GFAP; the disease is dementia.
