In seven m6A-RMRs upregulated in the autoimmune skin disease group, one m6A-RMR WTAP was shared by four autoimmune skin diseases; one m6A-RMR G3BP1 was shared by three autoimmune skin diseases including ACLE, CCLE, and psoriasis; one m6A-RMR PRRC2A was shared by three autoimmune skin diseases including CCLE, psoriasis, and SCLE; and one m6A-RMR G3BP2 was shared by two autoimmune skin diseases including CCLE and psoriasis. This evidence concerns the gene PRRC2A and psoriasis.
