Targeted Genomic Analysis of Blood and Tissue Samples From Patients With Cancer

Malignant Neoplasm

This research trial studies the use of targeted genomic analysis of blood and tissue samples from patients with cancer. Genomic sequencing is a laboratory method that is used to determine the entire genetic makeup of a specific organism or cell type. Genomic sequencing can be used to find changes in areas of the genome that may be important in the development of cancer. It may also help doctors improve ways to diagnose and treat patients with rare cancers with poor prognosis or lack of effective therapy.

Hairy Cell Leukemia Patient Data Registry

Leukemia, Other

The overall objective is to develop a clinical data registry that can be used to facilitate research with the ultimate goal of reducing the morbidity and/or mortality and improving the quality of life of patients diagnosed or living with hairy cell leukemia. With approximately 1,000 new cases of this rare disease identified in the US each year, HCL represents 2% of all cases of leukemia in adults. Considering the rarity of this chronic leukemia, the Hairy Cell Leukemia Foundation (HCLF), in partnership with investigators from its Centers of Excellence, seeks to develop a registry to help researchers identify new trends in outcomes, recognize the most effective treatments, discover previously unknown complications of the disease, and design clinical trials for new therapies.

The NIH MINI Study: Metabolism, Infection, and Immunity in Inborn Errors of Metabolism

Oxidative Phosphorylation Deficiencies Electron Transport Chain Disorders, Mitochondrial Mitochondrial Disorders Leigh Disease

The Metabolism, Infection and Immunity (MINI) Study is a longitudinal natural history study at the National Institutes of Health (NIH) that aims to define the relationship between infection, immunity and clinical decline in individuals with mitochondrial disease. Mitochondrial diseases are a group of disorders caused by problems with the cell s ability to produce energy. Infection in individuals with mitochondrial disease can lead to worsening clinical symptoms, particularly neurologic symptoms. Goals: The main goal of our study is to understand the relationship between infection and clinical decline in patients with mitochondrial disease. Mitochondrial diseases can affect many different parts of the body, including the immune system and its ability to respond to infection. Therefore, we perform a comprehensive evaluation of participants including a detailed immunologic assessment. We are not testing any new medicine or procedure to treat or cure IEM or mitochondrial diseases. However, by understanding the relationship between infection and mitochondrial disease, we hope to develop treatments in the future. At the NIH, we are interested in research. Although we do provide advice and care for people enrolled in our study, we are not able to take over the long-term care of participants. To enroll in our study, you (your child) must already have a confirmed diagnosis of a mitochondrial disease. We are not able to provide a "first time" diagnosis or regular metabolic care. What is involved? Once you contact our team members, you will be asked to provide medical records to determine eligibility. Our team will review the records and notify you if you (your child is) eligible to join the study. -Onsite participation: You (your child) will be invited to visit the National Institutes of Health in Bethesda, Maryland. This first visit will typically last 3-5 days. Depending on the level of participation, additional visits may be requested. Our team members will work with you and your child to coordinate the supports needed during your stay at NIH. Study participants may be seen in the clinic, day hospital or inpatient setting. When you (your child) arrive at the NIH we will have an informed consent discussion to confirm willingness to participate, answer questions and review the risks and benefits of the study. You (your child) will meet with a physician who will ask about medical and family history and do a physical exam (like in any doctor's office). We will ask all study participants to allow us to collect urine, draw blood, swab your (your child s) nose, and perform a detailed assessment. We may suggest additional evaluations or specialty consults for some participants based on clinical manifestations, age and level of independence. We will explain these studies to you (your child). They may include items such as- imaging studies, DEXA or MRI scan, energy expenditure or metabolic testing, developmental neuropsychological logical testing, physiatry, ophthalmology, or other consults. In some cases, we may request a skin biopsy (if one has not been done). You will receive the results of your (your child's) clinical testing and notes from any clinical consultations. -Remote participation: If you (your child) are unable to travel, you (your child) may be enrolled remotely for records review, questionnaires, and telethealth exams. Blood or other samples collection may be requested in coordination with local providers or lab testing companies...

Studying Childhood-onset Behavioral, Psychiatric, and Developmental Disorders

Neuropsychiatric Disorder Neurological Disorder Neurodevelopmental Disorder Sleep

Background: \- Many psychiatric, behavioral, and developmental disorders are genetic. This means that they tend to run in families. Some begin in childhood, while others do not appear until adulthood. Researchers want to look at people of all ages who have these disorders that started in childhood. They will also look at relatives of people with these disorders. This information will allow doctors to learn more about childhood behavioral problems and how they are inherited. It may also help doctors treat those disorders. Objectives: \- To study the onset and treatment of childhood behavioral, psychiatric, and developmental disorders. Eligibility: * Individuals of any age who have a psychiatric, autism spectrum, or developmental disorder, or other behavioral problems. * Family members of individuals with the above disorders. This group may include parents, grandparents, siblings, aunts/uncles, cousins, and children. Design: \- Participants will be screened with a medical history and physical exam. They may have a psychiatric history with tests of thinking, judgment, and behavior. Brain imaging scans may be performed to look at brain function.

Natural History Study of Progressive Multifocal Leukoencephalopathy (PML)

Progressive Multifocal Leukoencephalopathy

Background: \- Progressive multifocal leukoencephalopathy (PML) is a severe viral infection of the brain. It is caused by JC virus. Many people have this virus in their bodies all their life, but it is usually kept in check by their immune system. If the immune system does not work right because of a disease or medication, the virus becomes active and can damage cells in the brain. Not much is known about PML or how it affects the immune system. Researchers want to study people with PML to better understand the natural history of the disease. Objectives: \- To study the natural history of PML. Eligibility: \- Individuals at least 2 years of age who have PML. Design: * Participants will be screened with a physical exam, medical history, and imaging studies. * Participants will have several visits to the National Institutes of Health Clinical Center. There will be an initial visit, monthly visits for the next 6 months, a 12-month visit, and possible visits afterward. * At the initial visit, participants will give blood, urine, and spinal fluid samples. They will also have neurological tests and imaging studies of the brain. * For the next five visits, participants will give blood and urine samples. They will also have neurological tests and imaging studies of the brain. * The 6-month and 12-month visits will repeat the tests from the initial visit. * Other optional procedures include bone marrow samples and skin biopsies. Additional blood tests and imaging studies may be performed. * Treatment will not be provided as part of this study.

Lentiviral Gene Transfer for Treatment of Children Older Than Two Years of Age With X-Linked Severe Combined Immunodeficiency (XSCID)

X-linked Severe Combined Immunodeficiency (XSCID)

This is a Phase I/II non-randomized clinical trial of ex vivo hematopoietic stem cell (HSC) gene transfer treatment for X-linked severe combined immunodeficiency (XSCID, also known as SCID-X1) using a self-inactivating lentiviral vector incorporating additional features to improve safety and performance. The study will treat 35 patients with XSCID who are between 2 and 50 years of age and who have clinically significant impairment of immunity. Patients will receive a total busulfan dose of approximately 6 mg/kg/body weight (target busulfan Area Under Curve is 4500 min\*micromol/L/day) delivered as 3mg/kg body weight on day 1 and dose adjusted on day 2 (if busulfan AUC result is available) to achieve the target dose, to condition their bone marrow, and this will be followed by a single infusion of autologous transduced CD34+HSC. Patients will then be followed to evaluate engraftment, expansion, and function of gene corrected lymphocytes that arise from the transplant; to evaluate improvement in laboratory measures of immune function; to evaluate any clinical benefit that accrues from the treatment; and to evaluate the safety of this treatment. The primary endpoint of the study with respect to these outcomes will be at 2 years, though data relevant to these measures will be collected at intervals throughout the study and during the longer follow-up period of at least 15 years recommended by the Food and Drug Administration (FDA) Guidance "Long Term Follow-Up After Administration of Human Gene Therapy Products" https://www.fda.gov/media/113768/download for patients participating in gene transfer clinical trials. XSCID results from defects in the IL2RGgene encoding the common gamma chain (yc) shared by receptors for Interleukin 2 (IL-2), IL-4, IL-7, IL-9, IL-15 and IL-21. At birth XSCID patients generally lack or have a severe deficiency of T-lymphocytes and NK cells, while their B- lymphocytes are normal in number but are severely deficient in function, failing to make essential antibodies. The severe deficiency form of XSCID is fatal in infancy without intervention to restore some level of immune function. The best current therapy is a T-lymphocyte-depleted bone marrow transplant from an HLA tissue typing matched sibling, and with this type of donor it is not required to administer chemotherapy or radiation conditioning of the patient's marrow to achieve excellent engraftment and immune correction of an XSCID patient. However, the great majority of patients with XSCID lack a matched sibling donor, and in these patients the standard of care is to perform a transplant of T- lymphocyte depleted bone marrow from a parent. This type of transplant is called haploidentical because in general a parent will be only half- matched by HLA tissue typing to the affected child. Whether or not any conditioning is used, haploidentical transplant for XSCID has a significantly poorer prognosis than a matched sibling donor transplant. Following haploidentical transplant, XSCID patients are observed to achieve a wide range of partial immune reconstitution and that reconstitution can wane over time in some patients. That subset of XSCID patients who either fail to engraft, fail to achieve adequate immune reconstitution, or lose immune function over time suffer from recurrent viral, bacterial and fungal infections, problems with allo- or autoimmunity, impaired pulmonary function and/or significant growth failure. We propose to offer gene transfer treatment to XSCID patients\^3 \>= 2 years of age who have clinically significant defects of immunity despite prior haploidentical hematopoietic stem cell transplant, and who lack an HLA-matched sibling donor. Our current gene transfer treatment protocol can be regarded as a salvage/rescue protocol. Prior successful retroviral gene transfer treatment instead of bone marrow transplant (BMT) in Paris and London for 20 infants with XSCID has provided proof of principle for efficacy. However, a major safety concern is the occurrence of 5 cases of leukemia at 3-5 years after treatment triggered in part by vector insertional mutagenesis activation of LMO2 and other DNA regulatory genes by the strong enhancer present in the long-terminal repeat (LTR) of the Moloney Leukemia Virus (MLV)- based vector. Furthermore, previous studies of gene transfer treatment of older XSCID patients with MLV- based vectors demonstrated the additional problem of failure of adequate expansion of gene corrected T- lymphocytes to the very high levels seen in infants. To reduce or eliminate this leukemia risk, and possibly enhance performance sufficiently to achieve benefit in older XSCID patients, we have generated a lentivector with improved safety and performance features. We have generated a self-inactivating (SIN) lentiviral vector that is devoid of all viral transcription elements; that contains a short form of the human elongation factor 1a (EF1a) internal promoter to expres......

Normal Values in Hearing and Balance Testing

Healthy Volunteer

Background: \- Researchers at the National Institutes of Health give many tests of hearing and balance. These tests can help detect problems that affect hearing or balance. It is important to know exactly how healthy people perform on each of these tests. This information will indicate when a test result is normal and when a test result shows a problem. Researchers also want to determine the best methods for each test. Objectives: \- To test different types of hearing and balance tests, and collect information on normal values for each test. Eligibility: \- Healthy volunteers between 5 and 80 years of age. Design: * This study will require a single visit to the National Institutes of Health Clinical Center. It will include both screening tests and study tests of hearing and balance. Sometimes, a second visit may be required if a test is designed to measure the same thing on 2 different days. Each visit will last between 2 and 5 hours, depending on the number of tests scheduled per visit. * Participants will have a physical exam and medical history. They will also have basic tests to check for normal hearing and balance. * Participants may have different hearing tests, including the following: * Auditory Evoked Potentials to study how the ears and brain handle sound information. * Auditory Processing Tests to study how a person processes complex sounds like speech in background noise. * Tests of middle ear and inner ear function. * Participants may have different balance and inner ear tests, including the following: * Balance test on a tilting platform. * Different tests to measure how well the eyes, ears, and brain work together to help maintain balance. * Treatment will not be needed as part of this study.

Proton and Photon Consortium Registry (PPCR): A Multi Center Registry of Pediatric Patients Treated With Radiation Therapy

Pediatric Patients Treated With Radiation Therapy

In previous studies, Proton Beam Radiation Therapy (PBRT) has been found to show better results in treating patients with cancer, both because there is better control of where in the body the radiation is directed and because it is associated with less severe long term side effects. However, there is limited published data demonstrating these results. The goal of the Proton and Photon Consortium Registry (PPCR) is to enroll children treated with radiation in order to describe the population that currently receives radiation and better compare the short-term and long-term benefits of different types of radiotherapy. The data collected from this study will help facilitate research on radiation therapy and allow for collaborative research. The PPCR will collect demographic and clinical data that many centers that deliver radiation therapy already collect in routine operations.

Evaluating New Radiation Techniques for Cardiovascular Imaging

Coronary Disease

Title: Evaluating New Radiation Techniques for Cardiovascular Imaging Background: Cardiac CT angiography is associated with radiation exposure. Different methods of creating CT pictures have been developed to reduce the radiation dose to the subject. The purpose of this research study is to learn whether these low dose research imagings are accurate or predict subject outcomes. Cardiac CT is also used for diagnostic imaging of coronary artery disease and identification of abnormal cardiac structures. An additional purpose of this study is to monitor the progression of cardiac disease. Cardiac imaging software and AI are constantly evolving and requires validation for accuracy. Using existing scan data, updated image software reconstruction can be applied and compared to previous existing standard of care images. Objectives: \- To study new ways of taking pictures of the heart or blood vessels using computed tomography. Eligibility: \- Adults at least 18 years of age who will be having imaging studies to help detect heart or blood vessel problems. Design: * Participants will be screened with a physical exam and medical history. Blood samples will be taken to check kidney function. * Participants will have a CT scan of the heart and blood vessels. A contrast agent may be used to improve the quality of the images. The scanning session may last up to 2 hours. * Timing of and the need for follow up contact will depend on results from the initial scan and may be repeated to assess for late events. Telephone, office contact, or other follow-up of subjects may be done after CCTA to evaluate if the subject had subsequent cardiovascular testing. Further follow up will be based on reported test results.
