Gene Name Variant Alleles Chemical Phenotype Category Significance Notes Sentence Publications Annotation ID
CDA rs2072671 CC cytarabine "toxicity","metabolism/PK" not stated as determined by measurement of cytidine deaminase (CDA) activity, which detoxifies the drug. Variants in the TPMT and CDA gene were examined, and this variant genotype along with the rs3215400 del/del genotype in the CDA gene were identified as possibly being associated with the cytarabine-induced toxicity, and may correlate with the deficiency in CDA activity observed through disregulation of CDA expression. Genotype CC is associated with decreased clearance of cytarabine in children Lymphoma, T-Cell. 22379997 827922320
CDA rs2072671 AA gemcitabine metabolism/PK yes Blood samples were collected from NSCLC patients for genotyping, and CDA enzyme activity assay.

CDA rs2072671 AA + AC bevacizumab efficacy no No significant association with response, progression-free survival (PFS) or overall survival (OS) was seen between the genotypes in multivariable analysis. However, in univariate analysis, there was a "nominally" significant association with OS - patients with the AA or AC genotype had longer OS as compared to those with the CC genotype (p=0.036). Formally significant was defined as p<0.0026, and nominally significant as p<0.05. Genotypes AA + AC are not associated with response to bevacizumab, capecitabine, cisplatin, docetaxel, epirubicin, oxaliplatin or trastuzumab in people with Stomach Neoplasms as compared to genotype CC. 27995989 1448568292

CDA rs1048977 TT gemcitabine metabolism/PK yes 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. Although this SNP was not significantly associated with gemcitabine clearance, it was significantly associated with clearance of the gemcitabine metabolite dFdU. Pharmacokinetics of dFdU were described by a three-compartment model. CDA rs1048977 genotype and creatine clearance were significant covariates in the final model to be predict rate of clearance of dFdU, the deaminated metabolite of gemcitabine.

CDA rs2072671 AA gemcitabine efficacy yes Patients with the AA genotype had a better response to gemcitabine therapy than patients with either the AC or the CC genotype. However, progression free survival did not significantly differ between genotype groups. There were four SNPs in this study that, when taken together, affected progression free survival: rs183484, rs2072671, rs760370, and rs9937. Using patients with 0 or 1 variant as reference, patients with 2 variants had an increased HR of 1.79 (P = 0.004) and patients with 3-4 variants has an increased HR of 3.25 (P < 0.001). There were also two SNPs in this study that, when taken together, affected tumor response to therapy: rs2072671 and rs760370. Using patients with 0 variants as reference, patients with 1-2 variants had an increased OR of 3.40 (P = 0.004). Genotype AA is associated with increased response to gemcitabine in people with Pancreatic Neoplasms as compared to genotypes AC + CC. 20665488 981793945
