For instance, metaDEGs of the uveitis only group comprise genes that are involved in the innate immune response, such as chemokine receptors (CX3CR1, CCR1, and CCR2), and Toll-like receptors (TLR4, TLR7, TLR8, and the TLR4 homologous receptor, CD180). The gene discussed is CX3CR1; the disease is uveitis.
