Leucocyte chemotaxis was significantly enriched in the MMD group, and metabolism‐related genes (GGT1, BAAT and ADO) and EndMT (TGFβ1, SMAD2, SMAD3 and SMAD4) tended to be enriched in CD4+T and CD8+T cell subgroups (Figure 3A–C; Figure S11A). This evidence concerns the gene BAAT and multiminicore myopathy.
