Brief summary
The genotype profile of CYP2C8 was analyzed in a Korean population. Frequency in multi-ethnic population and in vivo functionality of novel null allelic CYP2C8 variant were evaluated.
Detailed description
Whole blood samples from 50 unrelated Korean subjects were genotyped for 3kb of 5' upstream region, all exon-intron boundaries, exons, and UTR regions of CYP2C8 gene by direct sequencing. Genotyping of CYP2C8 has been addressed only for null allelic variant, CYP2C8\*11 using pyrosequencing in the 447 Koreans, 93 African-Americans, 100 Caucasians, 348 Chineses and 100 Vietnameses. Then, in-vivo single PK study of CYP2C8 probe, rosiglitazone(4mg), was conducted in 7 healthy subjects with CYP2C8\*1/\*1 and 2 with CY2C8\*1/\*11.
Interventions
single oral administration of 4mg of rosiglitazone
CYP2C8\*11.
