FMO3 rs2266782 AA sulindac metabolism/PK yes Measures of exposure were AUC, Cmax, Tmax, and T1/2. Genotype AA is associated with increased exposure to sulindac in healthy individuals as compared to genotype GG. 28331852 1448613020
FMO3 rs2266780 GG sulindac metabolism/PK yes Measures of exposure were AUC, Cmax, Tmax, and T1/2. Genotype GG is associated with increased exposure to sulindac in healthy individuals as compared to genotype AA. 28331852 1448613027
FMO3 rs2266782 AA + AG nicotine metabolism/PK no This was described as a trend towards higher nicotine AUC. Participants received 4 mg oral nicotine. Genotypes AA + AG is associated with decreased metabolism of nicotine in CYP2A6 reduced, but not normal, metabolizers as compared to genotype GG. 24448396 1183703319
FMO3 rs2266780 AA nicotine metabolism/PK yes Individuals with the AA genotype have a greater percent of both deuterated nicotine and non-deuterated nicotine metabolized to nicotine-N-oxide as compared to the AG or GG genotype. Genotype AA is associated with increased metabolism of nicotine as compared to genotypes AG + GG. 28290528 1449157859
FMO3 rs2266782 G cotinine metabolism/PK no This SNP is not associated with the pharmacokinetic measures of cotinine. Measures include half-life, Cmax, AUC, non renal clearance, and total clearance. Allele G is not associated with metabolism of cotinine in people with Tobacco Use Disorder as compared to allele A. 28178031 1448602091
FMO3 rs2266782 G nicotine metabolism/PK no This SNP is not associated with the pharmacokinetic measures of nicotine. Measures include half-life, Cmax, AUC, non renal clearance, and total clearance. Allele G is not associated with metabolism of nicotine in people with Tobacco Use Disorder as compared to allele A. 28178031 1448602097
FMO3 rs2266782 AA itopride metabolism/PK yes The authors compared metabolism of itopride between 6 healthy volunteers with the GG genotype at rs2266782 and AA genotype at rs2266780 VERSUS 6 healthy volunteers with the AA genotype at rs2266782 and GG genotype at rs2266780. Several PK measurements were taken after a single dose of itopride including AUC of itopride and N-oxide itopride, Cmax of itopride and N-oxide itopride, as well as Tmax and half life of itopride. Only AUC and Cmax differed significantly between the two groups. Genotype AA is associated with decreased metabolism of itopride in healthy individuals as compared to genotype GG. 25224784 1184755585
FMO3 rs2266780 GG itopride metabolism/PK yes The authors compared metabolism of itopride between 6 healthy volunteers with the GG genotype at rs2266782 and AA genotype at rs2266780 VERSUS 6 healthy volunteers with the AA genotype at rs2266782 and GG genotype at rs2266780. Several PK measurements were taken after a single dose of itopride including AUC of itopride and N-oxide itopride, Cmax of itopride and N-oxide itopride, as well as Tmax and half life of itopride. Only AUC and Cmax differed significantly between the two groups. Genotype GG is associated with decreased metabolism of itopride in healthy individuals as compared to genotype AA. 25224784 1184755593
FMO3 rs1800822 CC tacrolimus metabolism/PK yes for donor genotype. Significant at weeks 2, 3, 4 and 1 month. Genotype CC is associated with increased dose-adjusted trough concentrations of tacrolimus in people with liver transplantation as compared to genotypes CT + TT. 28084894 1448569520
FMO3 rs909530 CC tacrolimus metabolism/PK yes for donor genotype. Significant at weeks 2, 3 and 1 month. Genotype CC is associated with increased dose-adjusted trough concentrations of tacrolimus in people with liver transplantation as compared to genotypes CT + TT. 28084894 1448569532
FMO3 FMO3 haplotype olanzapine metabolism/PK no no PMs were present. Disease is not specified explicitly but study subjects are referred to as patients and the introduction discusses use of olanzapine as for schizophrenia. FMO3 normal metabolizer genotype is not associated with clearance of olanzapine in people with Schizophrenia as compared to FMO3 intermediate metabolizer genotype. 26856397 1448631663
FMO3 rs2266780 AA voriconazole metabolism/PK yes in patients with hematopoietic stem cell transplantation and hematological malignancies. Genotype AA is associated with increased concentrations of voriconazole as compared to genotypes AG + GG. 31932875 1451122165
