A Natural History Study Seeks to Understand the Clinical, Genomic, Pharmacological, Laboratory, and Dietary Determinates of Pyrimidine and Purine Metabolism Disorders
Background Pyrimidine and purine metabolism disorders (DPPMs) affect how the body metabolizes chemicals called pyrimidines and purines. DPPMs can cause dysfunctions throughout the body, especially in the brain, blood, kidneys, and immune system. People with DPPMs might have no symptoms, mild symptoms, or they may have severe, chronic symptoms, that …
Studies of Disorders With Increased Susceptibility to Fungal Infections
Background Researchers are interested in studying disorders that make individuals more susceptible to fungal infections, specifically infections with the Candida yeast. These disorders are often related to problems with the immune system and may have genetic factors, which suggests that researchers should study not only the individual with the disorder, …
Human Movement Database
This study will collect information on the different ways people control limb and body movements. This information will be used to develop a database on normal movements and adaptive movements of people who have diseases that affect the way they move. The database will serve as a tool to improve …
A Natural History Study of Metabolic Sizing in Health and Disease
Background Scientists have long used simple measures (such as height and weight) to estimate how much a person s body uses food (calories) as energy, as commonly called the metabolic rate. But metabolism varies among people with similar body sizes. Scientists now believe the old formulas for estimating metabolic rates …
Collection of Blood From Patients With Cancer, Other Tumors, or Tumor Predisposition Syndromes for Genetic Analysis
Background Some genes may be associated with a greater chance of side effects during cancer treatment. These genes may also make certain treatments less effective. Researchers want to collect blood or cheek swab samples from people having cancer treatment to study these genes. Objectives To obtain a blood or cheek …
Cell Collection to Study Eye Diseases
Background Best Vitelliform Dystrophy (Best disease), Late-Onset Retinal Degeneration (L-ORD), and Age-Related Macular Degeneration (AMD) all affect the retina, the light sensing area at the back of the eye. Doctors cannot safely obtain retinal cells to study these diseases. However, cells collected from hair follicles, skin, and blood can be …
GEMINI-NSCLC: NSCLC Biomarker Study
Non-interventional study that will be collecting clinical and molecular health information from patients with NSCLC who will receive longitudinal blood collection in addition to their standard of care therapy and disease surveillance.
NIAID Centralized Sequencing Protocol
Background Genetic testing called "sequencing" helps researchers look at DNA. Genes are made of DNA and are the instructions for our bodies to function. We all have thousands of genes. DNA variants are differences in genes between two people. We all have lots of variants. Most are harmless and some …
Urinary Vitamin C Loss in Diabetic Subjects
Several studies have reported that diabetic subjects have lower plasma vitamin C concentrations than non-diabetic subjects. Although urinary vitamin C loss in diabetic subjects was reported to be increased in two studies, these are difficult to interpret due to lack of controlled vitamin C intake, inadequate sampling, lack of control …
Environmental Risk Factors for the Anti-synthetase Syndrome
Background Like other complex diseases, autoimmune diseases are the result of numerous causes, including genetic and environmental factors. Some researchers believe that people who are susceptible to autoimmune disorders develop them when the body reacts to environmental or other factors by creating white blood cells that attack the body s …
