Such as was done for astrocytes, we enrolled six patients with definite neuron-specific Ab-associated neurological disorders: anti-AK5+ AIE/PNS (n = 1), anti-PCA-Tr+ AIE/PNS (n = 1), anti-NMDAR+ AIE/PNS (n = 1), anti-Hu+ AIE/PNS (n = 2), and anti-Ri+ AIE/PNS (n = 1). This evidence concerns the gene AK5 and nervous system disorder.
