Our study also found several antibodies that were elevated in the sera of COVID-19 patients regardless of disease severity, including the acetylcholine receptor (IgA), α-synucleins (IgA), amyloid β peptide (IgA), dopamine 2 (D2) receptor (IgA), and myelin basic protein (IgA) (Table 1). The gene discussed is SNCA; the disease is COVID-19.
