Amino acid transitions induced by G1719T, A1726C, A1752G/T and BCP A1762T/G1764A mutants had higher prevalence of 39.7% (23/58), 29.3% (17/58), 27.6% (16/58) and 31.0% (18/58), which mainly occurred in genotype C (21/23), genotype B (16/17), genotype B (13/16) and genotype C (16/18) infection patients, respectively. This evidence concerns the gene OPN1SW and infection.
