In our AD EA TWAS, we also identified genes associated with other neurological and autoimmune diseases, including Parkinson’s disease (CYB561 [54] and SLC25A39 [55]), Crohn’s disease (ATG16L1 [56]), Amyotrophic lateral sclerosis (SIGLEC9 [57]), and Riboflavin Transport Deficiency (SLC52A1 [58]). The gene discussed is SIGLEC9; the disease is Parkinson disease.
