"Data suggest oseltamivir activation is associated with an SNP in CES1 (rs71647871 G143E); in liver from donors with genotype 143G/E activation is 40% of that from donors with genotype 143G/G. Hepatic CES1 expression in females is 17.3% higher than in males; oseltamivir activation rate in females is 27.8% higher than in males. (Liver tissues used were obtained from tissue banks located in the United States.)"xsd:string
