华法林表现出广泛的个体差异,部分是由 CYP2C9 和 VKORC1 变异介导的。 CALU(维生素 K 还原酶调节剂)的变异是否影响华法林剂量尚不清楚。我们对剂量异常值发现队列中的 CALU 区域进行了重新测序:具有高(>90%,n=55)或低(<10%,n=53)剂量需求的患者(在考虑了已知的遗传和非遗传变量后)。一种 CALU 变体 rs339097 与高剂量相关(p=0.01)。我们在两个复制队列中验证了该变异作为较高华法林剂量的预测因子:1)496 名混合种族患者,2)194 名非裔美国患者。 rs339097 的 G 等位基因(非洲裔美国人和白种人等位基因频率分别为 0.14 和 0.002)与第一个复制队列中治疗剂量高出 14.5%(SD±7%)(p=0.03)以及第二个复制队列中高于预测剂量相关(等位基因频率=0.14,单侧 p=0.03)。 CALU rs339097 A>G 与较高的华法林剂量需求相关,与非裔美国人华法林剂量的已知遗传和非遗传预测因素无关。
Warfarin demonstrates wide interindividual variability that is partly mediated by variants in CYP2C9 and VKORC1. Whether variants in CALU (vitamin K reductase regulator) influence warfarin dose is unknown. We resequenced CALU regions in a discovery cohort of dose-outliers: patients with high(>90th percentile, n=55) or low(<10th percentile, n=53) dose requirements(after accounting for known genetic and nongenetic variables). One CALU variant, rs339097, was associated with high-doses(p=0.01). We validated this variant as a predictor of higher warfarin doses in two replication cohorts: 1)496 patients of mixed ethnicity, 2)194 African-American patients. The G allele of rs339097(African-American and Caucasian allele frequency 0.14 and 0.002, respectively), was associated with a 14.5%(SD±7%) greater therapeutic dose(p=0.03) in the first replication cohort and a higher than predicted dose in the second replication cohort(allele frequency=0.14, one-sided p=0.03). CALU rs339097 A>G is associated with higher warfarin dose requirements independent of known genetic and nongenetic predictors of warfarin dose in African-Americans.
