Could your genes raise your blood pressure? new study investigates
NCT ID NCT07330804
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether a specific change in the Corin gene (called I555/P568) makes high blood pressure more likely in people of African descent in Guadeloupe. Researchers will compare 370 adults with and without high blood pressure to see if this gene variant is more common in those with the condition. The goal is to better understand why high blood pressure is so common in this population and how it might be linked to heart and kidney problems.
