NCT ID NCT02769975
First seen Jun 27, 2026 · Last updated Aug 14, 2026 · Updated 5 times
Summary
This study enrolls up to 15,000 children with known or suspected endocrine or metabolic disorders, along with their family members. Researchers will collect medical records, blood, saliva, and other samples to identify genetic changes linked to these conditions. The goal is to better understand how these disorders are inherited and to improve future diagnosis and treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this research could uncover genetic roots of rare endocrine and metabolic disorders, pointing toward better diagnostic tests and potential treatments.
- What could go wrong
- This is an observational study, not a treatment trial. It may not directly benefit participants, and genetic findings may take years to translate into therapies.

Who is studied
Children with endocrine or metabolic-related condition(s) who may or may not be eligible for a specific NICHD research protocol, may be evaluated under the auspices of this protocol to advance the clinical skills of physicians participating in NICHD clinical research and training programs, and to provide stimuli for new clinical research initiatives.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
* INCLUSION CRITERIA: In order to be eligible to participate in this study, an individual must meet all of the following criteria: * Participants with known or suspected endocrine disorder age 3 months-18 years are eligible for this protocol. * Relatives ages 3 months-100 years may be enrolled if clinically indicated for the diagnosis of a proband. EXCLUSION CRITERIA: An individual who meets any of the following criteria will be excluded from participation in this study: * Lack of suspected endocrine disorders. * 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 patient, will exclude participation. Patients 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 NICHD resources will be excluded.
