Study Summary

Background:

There are many endocrine and metabolic-related conditions. Two well-known disorders include diabetes and thyroid disease. Some of these diseases are caused by a change in genes. Researchers want to identify the genes involved in these disorders. They hope this will help them learn more about these diseases.

Objectives:

To learn more about conditions that affect the hormone-secreting glands (endocrine glands) in adults. To train doctors to diagnose and treat people with endocrine or metabolic conditions.

Eligibility:

Adults age 18 years and older with a known or suspected endocrine disorder.

Relatives ages 18 years and older.

Doctors will review all requests and available medical records to determine final eligibility for the protocol.

Design:

Participants will have a medical history and physical exam.

Most participants will have 1 visit, and may have follow up visits if necessary. They may have tests, surgery, or other procedures to help diagnose or treat their condition. These could include:

  • Blood, urine, and saliva tests

  • Imaging tests. These may include X-ray, ultrasound, or scans.

  • Sleep study

  • Medical photographs

  • Visits with other specialists at NIH

Participants will provide blood, urine, saliva, or tissue samples. Some of these samples may be stored in the freezer for future studies.

Participants may be asked to participate in genetic testing. They will give a blood or saliva sample for this.

Eligibility Criteria

Inclusion

  • INCLUSION CRITERIA:

  • Participants with known or suspected endocrine disorder age 18 years and older areeligible for this protocol. Protocol investigators will make the actual selection ofsubjects most appropriate for clinical evaluation.

  • Relatives ages 18 years and older may be enrolled if clinically indicated for thediagnosis of a proband.

Exclusion

EXCLUSION CRITERIA:

  • Anyone under the age of 18 years old

  • Any medical, physical, psychiatric, or social conditions, which, in the opinion ofthe investigators, would make participation in this protocol not in the bestinterest of the subject. Subjects who are critically ill, unstable, or with severeorgan failure that may affect/limit the endocrine evaluation and place unsustainabledemands on Clinical Center or NIDDK resources.

Study Description

This is an observational protocol designed to collect data from adult subjects with known or suspected endocrine or metabolic disorders.

OBJECTIVE: The overall purpose of endocrine evaluations under this protocol is to increase knowledge of endocrine or metabolic diseases. Adults with known or suspected endocrine or metabolic-related condition(s) may be evaluated under this protocol for:

  1. Collection of data for endocrine related conditions (case reports, case series)

  2. Collection of data for future research

  3. Collection of samples, including leftover samples from clinically indicated tests, for future research (including genomics)

METHODS: Patients will undergo a history and physical exam, anthropometrics, vital signs and endocrine laboratory studies.
