AICDA and systemic lupus erythematosus: We finally identified 21 protein-AID pairs showing strong evidence of colocalization (PP.H4 > 0.75) in six AIDs (3 for hypothyroidism, 5 for IBD, 2 for MG, 1 for PA, 2 for SLE, and 8 for T1D), among which protein encoded by CTSH is associated with both T1D and MG, with details provided in Table S13 and Fig S3.
