Clinical, Genetic, and Epidemiologic Study of Children and Adults With RASopathies
Background RASopathies are a group of conditions caused by a genetic change. People with a RASopathy may have developmental issues, cognitive disability, poor growth, and birth defects. They may also have an increased risk for developing cancer. Researchers want to learn more. Objective: To learn more about RASopathies, how genes …
Clinical Manifestations and Biomarkers in Amyotrophic Lateral Sclerosis Type 4 and Other Inherited Neurological Disorders of RNA Processing
Background Amyotrophic lateral sclerosis type 4 (ALS4) is an inherited motor neuron disease. People with ALS4 have a change in the amount of RNA and DNA that bind together. This binding of RNA with DNA forms units called R-loops. Researchers want to learn how R-loops are related to ALS4. To …
VRC 900: Evaluation of Tissue-Specific Immune Responses in Adults 18 Years of Age and Older
Background The Vaccine Research Center (VRC) is dedicated to understanding immune responses associated with prevention and treatment of infectious diseases. To study these immune responses, researchers need to collect specimens and images from individuals who have recently had a vaccination or recovered from an infection. These specimens and images are …
Clinical and Genetic Studies in Familial Non-medullary Thyroid Cancer
Background Researchers are studying types of thyroid cancer that seem to cluster in families. Non-medullary thyroid cancer accounts for the vast majority of all types of thyroid cancer, but little is known about possible genes that may cause the cancer. More research is needed to develop the best ways to …
Cerebral Palsy and the Study of Brain Activity During Motor Tasks
Background Two ways to study the brain while people are moving are near-infrared spectroscopy (NIRS) and electroencephalography (EEG). NIRS uses light to look at blood flow in the brain when it is active. EEG records electrical activity in the brain. Both have been used safely for many years, even in …
Pathological Basis of MRI Signal Changes in Multiple Sclerosis
Background Multiple sclerosis (MS) is a disease that damages the central nervous system (brain and spinal cord). This leads to increased physical disability over time. The disease is lifelong once it begins. Researchers want to learn more about MS s stages and follow them until a person s death. Objective …
Liver Disease in Urea Cycle Disorders
This is a multi-center, cross-sectional study to assess risk for liver fibrosis and hepatic injury in individuals with urea cycle disorders (UCDs) using serum biomarkers, Fibroscan, and MRE. This study will be conducted at 5 sites of the Urea Cycle Disorders Consortium: Baylor College of Medicine in Houston, TX, Seattle …
Rare Tumors and Cancer Predisposition in Individuals and Families
Background Some people may be prone to develop cancer for many reasons. Factors that affect their risk include the genes they inherit and the environment they live and work in. Researchers want to learn more about the natural history of cancer. Objective To understand how genes and environmental factors can …
Immune Regulation in Patients With Common Variable Immunodeficiency and Related Inborn Errors of Immunity (IEI)
This study aims to understand the causes and progression of Common Variable Immunodeficiency (CVID) and related inborn errors of immunity (IEI). These are conditions where the immune system does not function properly, leading to frequent infections and other complications such as gastrointestinal inflammation, lung and liver disease, autoimmune conditions, and …
Send-In Sample Collection for Comprehensive Analyses of Innate and Adaptive Immune Responses During Acute COVID-19 and Convalescence
Background Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes coronavirus disease 2019 (COVID-19). The global outbreak of COVID-19 is a major public health problem. COVID-19 causes a wide range of symptoms. These symptoms range from mild breathing problems to life-threatening problems or death. Some people have no symptoms. This study …
