There is one clinical trial.
The aim of this study is to evaluate the conversion of OP to OC in individual X and the family member of individual X. The investigators hypothesize that one or more of the single nucleoprotein polymorphisms (SNPs) of the CES1 gene represent a clinically important functional polymorphism.
However, some CES1 variants (V21I, and R182H) have a higher rate of oseltamivir metabolism compared to wild-type. --- V21I ---
Description: Conversion of Oseltamivir at 2 and 4 hours post doseMeasure: Tmax Time: 2 and 4 hours
Description: Document the sequence of all 14 exons of CES1 from individual X and the family members of individual X.Measure: Conversion of oseltamivir phosphate to oseltamivir carboxylate Time: one year (anticipate)
