Furthermore, a study looking into the relations between genetic variation and WNV-induced encephalitis in Camargue horses found a correlation between compound two genotypes of single nucleotide polymorphisms (SNPs) and immune-related candidate genes such as mitochondrial antiviral-signaling protein (MAVS), natural cytotoxicity triggering receptor 2 (NCR2), and interleukin 10 (IL-10). The gene discussed is MAVS; the disease is viral encephalitis.
