There are disclosed methods and kits for identifying a subject having genetic predictors of predisposition to abnormal international normalized ratio (INR) fluctuation during warfarin therapy. In an embodiment, a method includes testing the subject to check for a presence of a predetermined genetic variation. The predetermined genetic variation is correlated with abnormal INR fluctuation during warfarin therapy. The subject is identified as having a predisposition to abnormal INR fluctuation during warfarin therapy when the testing indicates the presence of the predetermined genetic variation. In one embodiment, a kit includes a test to check the subject for a presence of a predetermined genetic variation. The predetermined genetic variation is correlated with abnormal INR fluctuation during warfarin therapy. The kit includes an indicator to identify the presence of the predetermined genetic variation so as to identify the subject as having a predisposition to abnormal INR fluctuation during warfarin therapy.
