SLC22A2 rs316019 A tipiracil hydrochloride efficacy no The SNP was tested for association alone and with three other SNPs after univariate and multivariate analysis in a training (N= 52, Japan) and testing cohorts (N = 127, Italy). It was not significantly associated with progression-free or overall survival in either cohort. Allele A is not associated with response to tipiracil hydrochloride and trifluridine in people with Colorectal Neoplasms as compared to allele C. 28992563 1449146823
SLC22A2 rs316019 C metformin metabolism/PK no Allele C is not associated with exposure to metformin as compared to allele A. 29352482 1449165153
SLC22A2 rs145450955 GG lamivudine metabolism/PK no No significant differences in various pharmacokinetic parameters were seen between the genotypes. These included apparent oral clearance (p = 0.328), maximum plasma concentration (p = 0.314), time to reach max plasma concentration (p = 0.701), half-life (p = 0.734), area under the concentration-time curve from 0 to 24h (p = 0.693), area under the concentration-time curve from 0 to infinity (p = 0.701), renal clearance (p = 0.851), creatinine clearance (p = 0.588) and apparent tubular secretion clearance (p = 0.859). Please note alleles have been complemented to the plus chromosomal strand. Genotype GG is not associated with clearance of lamivudine in healthy individuals as compared to genotype AG. 23252721 1184168575
SLC22A2 rs316019 CC l-tryptophan metabolism/PK yes A gene dose effect was observed in that clearance of tryptophan decreased in the following manner: CC>AC>AA. Genotype CC is associated with increased clearance of l-tryptophan as compared to genotypes AA + AC. 22590580 982046569
SLC22A2 rs316019 CC metformin metabolism/PK yes Healthy individuals with the CC genotype had decreased area under the serum concentration-time curve from zero to infinity (AUCinf), decreased peak concentration (Cmax), and increased clearance (CL/F) of metformin, as compared to those with the AC genotype. Please note alleles have been complemented to the plus chromosomal strand. Genotype CC is associated with increased clearance of metformin in healthy individuals as compared to genotype AC. 23417334 1183682332
SLC22A2 rs316019 A metformin metabolism/PK no Allele A is not associated with steady-state concentration of metformin in healthy individuals as compared to allele C. 25939711 1446898150
SLC22A2 rs316009 TT metformin efficacy yes using computational model-based approaches and genetic, demographic, and long-term HbA1c data from 1,056 patients. Genotype TT is associated with increased response to metformin in people with Diabetes Mellitus as compared to genotypes CC + CT. 27415606 1448267827
SLC22A2 rs316019 A metformin efficacy no This variant is not associated with metformin glycemic response assessed as HbA1c reduction in patients on metformin monotherapy. Allele A is not associated with response to metformin in people with Diabetes Mellitus, Type 2 as compared to allele C. 27859023 1448631760
SLC22A2 rs316019 A sulfonamides, urea derivatives efficacy no Allele A is not associated with response to sulfonamides, urea derivatives in people with Diabetes Mellitus as compared to allele C. 29681852 1449310690
