Aim: LG72 can increase mitochondrial ROSs and oxidative stress has been implicated in the pathophysiology of amyotrophic lateral sclerosis (ALS). The serum level of LG72 or LG72-related molecules might therefore be associated with ALS. Here, we aim to determine the serum autoantibody against LG72 has potential as a biomarker for the diagnosis of ALS. Materials: Seventy-eighty patients with ALS, 45 patients with AD, 43 patients with PD and 88 healthy adults were enrolled. Results: The concentration of serum autoantibody against LG72 was more than fourfold lower in ALS than other control groups (p < 0.001). The AUC was 0.9627 when the cut-off value for autoantibody concentration was 0.167 g/ml. Conclusion: This finding suggests that the autoantibody against LG72 might serve as a surrogate biomarker for ALS.
