NT5C3A rs3750117 AA gemcitabine "other","metabolism/PK" yes AA vs AG vs GG. Also, significantly increased elimination clearance of dFdU was seen in patients with the GG genotype vs AA+AG p=0.037. dFdU = 2',2'-difluorodeoxyuridine (gemcitabine is inactivated to this less potent metabolite). Association with clinical outcomes was not reported. Genotype AA is associated with increased clearance of gemcitabine in people with Neoplasms as compared to genotype GG. 22838949 978639890
NT5C3A rs6946062 TT gemcitabine metabolism/PK no Gemcitabine, dFdCTP, and dFdU plasma concentrations were measured before (5, 15, 30, 45 min) and after gemcitabine infusion (1, 1.25, 1.5, 2, 6, 24, 48, 72 hrs). Population pharmacokinetic analysis of gemcitabine and metabolites (dFdU, dFdCTP) were performed by non-linear mixed effects modeling. rs6946062 is not associated with metabolism of gemcitabine. Genotype TT is not associated with metabolism of gemcitabine as compared to genotypes CC + CT. 24300978 1184174889
