Natural History of Thyroid Function Disorders

Participants in this study will be patients diagnosed with or suspected to have a thyroid function disorder. These conditions may include: hypothyroidism, hyperthyroidism, thyroid hormone resistance, Graves' Dermopathy, and thyroid-stimulating hormone (TSH) secreting pituitary adenomas. The main purpose of this study is to further understand the natural history, clinical presentation, and genetics of thyroid function disorders. Many of the tests performed are in the context of standard medical care that is offered to all patients with thyroid function disorders. In addition, blood and tissue samples may be taken for research and genetic studies.
