However, rs4929984 is significantly associated with the diastolic blood pressure level of IS patients (additive model: P<sub>adj</sub> = 0.007; dominant model: P<sub>adj</sub> = 0.013), whereas rs217727 is associated with international normalized ratio (additive model: P<sub>adj</sub> = 0.019; recessive model: P<sub>adj</sub> = 0.004), prothrombin time activity level (additive model: P<sub>adj</sub> = 0.026; recessive model: P<sub>adj</sub> = 0.004), and homocysteine level (recessive model: P<sub>adj</sub> = 0.048) in patients with IS.
Conclusion In conclusion, our findings suggest that the H19 rs217727 gene polymorphism contributes to small vessel ischemic stroke susceptibility in the Chinese Han population and may serve as a potential indicator for ischemic stroke susceptibility.
