Participants who self-report a medical diagnosis of preeclampsia or related hypertensive disorders of pregnancy (HDP), their family members, and women who have never had a diagnosis of preeclampsia (controls) will be invited to participate in this registry. Data will be collected on family members (including children) as reported by the participating individual. Minors who have been affected by preeclampsia, such as teens, will be allowed to participate with consent provided by a parent or guardian as well as assent given by the minor. The registry and informed consent may be completed by an authorized representative on behalf of a woman with a history of preeclampsia if she is physically or mentally disabled or is deceased.
