This suggests that RPL9 may participate in a regulatory network influencing T-cell subpopulations in collaboration with other genes and signaling molecules.Roya Ramezankhani research revealed that the RPL9 gene, housing both estrogenic and androgenic precursors, has implications in the pathogenesis of systemic immune disorders like lupus erythematosus and rheumatoid arthritis. The gene discussed is RPL9; the disease is lupus erythematosus.
