CALU rs339097 G warfarin dosage no Samples, genotypes and INRs from a cohort of 551 patients were used to derive an algorithm which was used to predict daily warfarin maintenance dose in a second cohort of 236 patients. Note: the authors state that "SNPs were tested for deviations from HWE using the chi-squared test, and for their association with the warfarin dose by Spearman correlation analysis using a *co-dominant* model." Allele G is not associated with dose of warfarin in people with heart valve replacement as compared to allele A. 25126975 1184757033
CALU rs339097 G warfarin dosage yes Allele G is associated with increased dose of warfarin. 20200517 637879876
CALU rs2290228 A warfarin dosage no in Korean patients with mechanical cardiac valves. Allele A is not associated with decreased dose of warfarin as compared to allele G. 22549502 1184510047
CALU rs339097 AG + GG warfarin dosage no A p value of 0.04 was given for dose- genotype association, but the authors stated that this association did not reach significanc in multiple regression testing (p = 0.066), and that was likely due to insufficient power.Variant allele carriers required 14.1 mg/week more warfarin than AA. Genotypes AG + GG are associated with increased dose of warfarin as compared to genotype AA. 21228733 827864550
CALU rs339097 G warfarin dosage yes Allele G is associated with increased dose of warfarin. 20200517 608431797
CALU rs339097 G warfarin dosage yes Allele G is associated with increased dose of warfarin. 20200517 637879873
CALU rs1043550 A warfarin dosage no No significant differences in therapeutic warfarin dose (mg/wk) or error in predicted dose were seen between any of the genotypes (AA, AG, GG). Note that the study cohort differed from Hardy-Weinberg equilibrium. Allele A is not associated with dose of warfarin as compared to allele G. 23656803 1184165651
CALU rs2290228 A warfarin dosage no Neither the addition of race, number of concurrent medications nor the number of concurrent medications interacting with warfarin enhanced algorithm performance. Similarly, consideration of CYP4F2, CALU or GGCX variant genotypes did not improve algorithms. Allele A is not associated with dose of warfarin as compared to allele G. 20128861 1184472408
CALU rs1043550 AA phenprocoumon "dosage","metabolism/PK" yes Daily dose of phenprocoumon is not significantly associated with this SNP. Daily dose is negatively correlated with age. This study published an algorithm for daily dose that includes height, although height was not significant in univariate analysis. This SNP is also not significantly associated with phenprocoumon concentration. Genotype AA is not associated with increased dose of phenprocoumon as compared to genotypes AG + GG. 21110013 982046676
CALU rs1043550 AA acenocoumarol dosage no The AA patients needed lower doses than g carriers (15.8 ± 5.9 mg/week vs. 18.1 ± 5.9 mg/week, respectively), although these differences did not reach statistical significance. Carriers of this variant and VKORC1 rs9934438 variant (27% of the sample) achieved the highest INR [2.26 (1.70-3.32)] and required the lowest dose (14.1 +/- 5.1 mg week(-1)). Genotype AA is associated with decreased dose of acenocoumarol as compared to genotypes AG + GG. 17596133 1444707135

Note: the authors state that "SNPs were tested for deviations from HWE using the chi-squared test, and for their association with the warfarin dose by Spearman correlation analysis using a *co-dominant* model." Allele G is not associated with dose of warfarin in people with heart valve replacement as compared to allele A. 25126975 1184757003
CALU rs1043550 G acenocoumarol dosage yes Normalized maintenance dose (NMD): mean maintenance dose/INR at equilibrium). A final multivariate regression model explained 48.1% of the global inter-individual variability in dose requirement. The authors created a clinical algorithm (CA) using patient’s clinical and demographic variables used in the PA. Allele G is associated with increased dose of acenocoumarol in people with Atrial Fibrillation as compared to allele A. 29479633 1449188291
CALU rs1043550 G warfarin dosage no Allele G is not associated with dose of warfarin as compared to allele A. 28049362 1449246724
