We found four pathways (Supplementary Table S3A) in common between T2D and COVID-19 using iGSEA4GWAS: the chemokine binding, G-protein coupled chemoattractant receptor activity pathways (CCR2 and CCR3), the TFAP2 family pathway (TFAP2B), and the ventricular cardiac muscle cells differentiation pathway (RARB and PROX1) in the canonical pathway and gene ontology database. This evidence concerns the gene CCR2 and COVID-19.
