Additionally, Genome-wide Association Studies (GWAS) have identified non-HLA genetic variants that contribute to MS susceptibility, including IL-2RA (rs2104286), IL-7R (rs6897932), CD40 (rs1883832 T), CD58 (rs2300747), and others, each playing a role in immune regulation and disease progression. Here, CD58 is linked to myeloid sarcoma.
