Observational Study of Endocrine and Metabolic Conditions

This is an observational study looking at adults with known or suspected endocrine (hormone-related) or metabolic (body chemistry) disorders. Researchers want to learn more about these conditions, including how they are diagnosed, managed, and treated. They also aim to train doctors in this area. The study will collect information and samples from participants to help understand these diseases better, potentially identifying genes involved. The goal is to increase knowledge about these conditions by December 31, 2036. Adults aged 18 to 100 years with a known or suspected endocrine disorder, or their relatives, may be able to join.

Study design
This is an observational study planning to enroll 1250 adult participants. It is not a treatment study but focuses on collecting data.
What's involved
Participants will undergo a physical exam, have their measurements taken (anthropometrics), vital signs checked, and endocrine lab tests.
Compensation
Not stated in the trial record.
Follow-up
The primary endpoint for data collection is measured at December 31, 2036, indicating a long-term data collection period.

Eligibility criteria

Inclusion

Participants with known or suspected endocrine disorder age 18 years and older are eligible for this protocol. Protocol investigators will make the actual selection of subjects most appropriate for clinical evaluation.
Relatives ages 18 years and older may be enrolled if clinically indicated for the diagnosis of a proband.

Exclusion

Anyone under the age of 18 years old
Any medical, physical, psychiatric, or social conditions, which, in the opinion of the investigators, would make participation in this protocol not in the best interest of the subject. Subjects who are critically ill, unstable, or with severe organ failure that may affect/limit the endocrine evaluation and place unsustainable demands on Clinical Center or NIDDK resources.
