Salt Loading and Thiazide Intervention Study

Summary

The investigators of this study propose to examine the relationships between STK39 (Serine Threonine Kinase 39) genotypes and responses to salt loading and to thiazide diuretics, hydrochlorothiazide. The investigators hypothesize that STK39 genotypes will be associated with the outcome of both interventions and can contribute to personalized care for hypertension.
