NCT00001147

Brief Summary

This study involves sampling blood from both normal volunteers and patients with diseases known or suspected to involve body chemicals called catecholamines. The blood will be used to establish normal values for plasma levels of catecholamines and related neurochemicals; to test for abnormal neurochemical patterns in patients; and to establish a "bank" of DNA from normal volunteers and from patients to be used in future studies about possible alterations of catecholamine-related genes. Study participants will report to NIH after fasting overnight except for water or noncaloric, noncaffeinated beverages. They must not have taken Tylenol for at least 5 days. Blood will then be drawn. DNA will be extracted and stored in the freezer for future studies.

Eligibility Criteria

Sexall
Healthy VolunteersYes
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • The subjects are healthy normal volunteers or patients with dysautonomia, pheochromocytoma, hypertension, or neurogenetic diseases involving catecholaminergic systems. Children of any age above 4 years may participate. In the case of minors, consent is obtained from an adult who is legally responsible for the subject.

You may not qualify if:

  • Subjects in whom anatomic or technical factors preclude insertion of an arm intravenous (i.v.) catheter are excluded. Normal volunteers taking any prescribed medication are excluded. Normal volunteers who smoke cigarettes or consume alcohol daily are excluded.
