P2RX7 and ocular toxoplasmosis: The observed disequilibrium in the distribution of the rs2230912 allele between individuals with and without ocular toxoplasmosis, along with the significant differences in IL-1β levels in patients with ocular toxoplasmosis and the rs1718119 alleles of the P2RX7 gene as previously described [60], suggests a linkage between this gene and the pathology of ocular toxoplasmosis.
