Without an explanation for severe and sometimes life-threatening symptoms, patients and their families are left in a state of unknown. Many individuals find themselves being passed from physician to physician, undergoing countless and often repetitive tests in the hopes of finding answers and insight about what the future may hold. This long and arduous journey to find a diagnosis does not end for many patients- the Office of Rare Diseases Research (ORDR) notes that 6% of individuals seeking their assistance have an undiagnosed disorder. In 2008, the National Institutes of Health (NIH) Undiagnosed Diseases Program (UDP) was established with the goal of providing care and answers for these individuals with mysterious conditions who have long eluded diagnosis. The NIH UDP is a joint venture of the NIH ORDR, the National Human Genome Research Institute Intramural Research Program (NHGRI-IRP), and the NIH Clinical Research Center (CRC) (1-3). The goals of the NIH UDP are to: (1) provide answers for patients with undiagnosed diseases; (2) generate new knowledge about disease mechanisms; (3) assess the application of new approaches to phenotyping and the use of genomic technologies; and (4) identify potential therapeutic targets, if possible. To date, the UDP has evaluated 3300 medical records and admitted 750 individuals with rare and undiagnosed conditions to the NIH Clinical Center. The NIH UDP has identified more than 70 rare disease diagnoses and several new conditions. The success of the NIH UDP prompted the NIH Common Fund to support the establishment of a network of medical research centers, the Undiagnosed Diseases Network (UDN), for fiscal years 2013-2020. The clinical sites will perform extensive phenotyping, genetic analyses, and functional studies of potential disease-causing variants. The testing performed on patients involves medically indicated studies intended to help reach a diagnosis, as well as research investigations that include a skin biopsy, blood draws, and DNA analysis. In addition, the UDN will further the goals of the UDP by permitting the sharing of personally identifiable phenotypic and genotypic information within the network. By sharing participant information and encouraging collaboration, the UDN hopes to improve the understanding of rare conditions and advance the diagnostic process and care for individuals with undiagnosed diseases.

People of all ages with various eye conditions, including genetic conditions, eye movement disorders, inflammatory eye diseases, retinal diseases and external eye diseases, may be eligible for this study. Participants undergo various tests and procedures to diagnose or evaluate their eye disease. The procedures may include the following: - Personal and family medical history - Physical examination and blood tests, including genetic testing. - Eye examination with dilation to measure visual acuity and eye pressure and to examine the front and back parts of the eye. - Questionnaire about vision and daily activities. - Conjunctival swab or lacrimal bland biopsy, or both: A sample of cells from the eyes is collected by swabbing the surface of the eye or by surgically removing a small sample of the surface of the eye or tear gland. - Electroretinogram to examine retinal function: The subject sits in the dark with his or her eyes patched for 30 minutes. The patches are removed, the surface of the eyes is numbed, and contact lenses that can sense signals from the retina are placed on the eyes. The subject then watches flashing lights. - Fluorescein angiography to examine the blood vessels in the eye: A dye is injected into a vein in the arm. The dye travels through the veins to the blood vessels in the eyes. A camera takes pictures of the dye as it flows through the blood vessels. - Optical coherence tomography to measure retinal thickness: A machine used to examine the eyes produces cross-sectional pictures of the retina. - Microperimetry to test how sensitive different parts of the retina are to changing levels of light. The subject sits in front of a computer and presses a button when he or she sees a light on the screen. - Oculography to record eye movements: Eye movements are measured by contact lenses or goggles that the subject wears while watching a series of spots on a computer screen.

Background: Blood cancers (such as leukemias) can be hard to treat, especially if they have mutations in the TP53 or RAS genes. These mutations can cause the cancer cells to create substances called neoepitopes. Researchers want to test a method of treating blood cancers by altering a person s T cells (a type of immune cell) to target neoepitopes. Objective: To test the use of neoepitope-specific T cells in people with blood cancers Eligibility: People aged 18 to 75 years with any of 9 blood cancers. Design: Participants will have a bone marrow biopsy: A sample of soft tissue will be removed from inside a pelvic bone. This is needed to confirm their diagnosis and the TP53 and RAS mutations in their cancer cells. They will also have a skin biopsy to look for these mutations in other tissue. Participants will undergo apheresis: Blood will be taken from their body through a vein. The blood will pass through a machine that separates out the T cells. The remaining blood will be returned to the body through a different vein. The T cells will be grown to become neoepitope-specific T cells. Participants receive drugs for 3 days to prepare their body for the treatment. The modified T cells will be given through a tube inserted into a vein. Participants will need to remain in the clinic at least 7 days after treatment. Participants will have 8 follow-up visits in the first year after treatment. They will have 6 more visits over the next 4 years. Long-term follow-up will go on for 10 more years.

Study Description: Despite the availability of pharmacotherapy for some substance use disorders, relapse vulnerability is still a significant issue. This suggests medications with alternative mechanisms of action should be explored to address this unmet need. Substantial preclinical research indicates that orexin antagonism blunts the internally and externally triggered motivation to attain abused substances. This research project will translate these preclinical findings into the clinical domain by administering the FDA approved orexin antagonist, suvorexant, to those with a substance use disorder. Suvorexant s ability to blunt neurobiological correlates of substance misuse will be assessed. This will be assessed following acute and repeated drug administration. Baseline individual differences will be considered to determine whether neurobiological variance influences suvorexant s impact in those with nicotine dependence. In an independent arm, the interaction between suvorexant and a dopamine agonist (methylphenidate) on cognitive function will be assessed in non-smoking individuals. Objectives: The objective is to determine the acute and chronic impact of the orexin antagonist, suvorexant, on neurobiological and behavioral factors linked with substance use disorders. Whether such effects are mediated by baseline characteristics will be tested. Given suvorexant is an FDA approved treatment for insomnia, sleep will be evaluated as well in the nicotine dependent arm. Endpoints: In nicotine-dependent individuals, suvorexant s impact on brain function will be assessed several ways by evaluating: 1) resting function, 2) reactivity to drug cues, 3) reactivity to non-drug related cognitive tasks. Sleep and nicotine use will be measured throughout the study period. In those without nicotine-dependence, the impact of suvorexant and the interaction of acute methylphenidate and suvorexant on brain function will be assessed. This arm will provide insight into how suvorexant impacts reward/cognition as well as impacts the pharmacological influence of methylphenidate on those same measures. Study Population:<TAB> Nicotine dependence arm:140 subjects; Volunteers who are between the ages of 18-60 and are daily smokers/vapers. Control arm: 80 subjects; Volunteers who are between the ages of 18-60 and are non-smokers/vapers This study will be conducted at the NIDA-IRP, Biomedical Research Center, in Baltimore, MD. Description of Study Intervention: Nicotine dependence arm: Suvorexant at 10 mg single dose, and Suvorexant at 10 mg daily for approximately 7 days. Control arm: 1. Tolerability visit with one MRI scan post-20mg methylphenidate, 4 acute drug administration (6-14 days in randomized order: 1. Placebo + placebo; 2. 20mg suvorexant + Placebo; 3. Placebo + 40mg methylphenidate; 4. 20 mg suvorexant + 40mg methylphenidate max) Study Duration: 5 years Participant Duration: 1-2 months

Background: - Pleuropulmonary blastoma (PPB) is a rare fast-growing lung tumor that is associated with other, rare tumor types. Most cases of PPB appear in children younger than 6 years of age. Recently, it has been shown that this condition can be inherited (e.g., mutation of the DICER1 gene). Researchers are studying both clinical and genetic aspects of this newly described condition. They are interested in collecting further medical history and genetic information on individuals and close relatives of individuals who have PPB or other rare associated tumors. Objectives: - To study individuals with a personal or a family history of pleuropulmonary blastoma (PPB) or other rare tumors that can be associated with PPB (e.g., cystic nephroma, nasal chondromesenchymal hamartoma, ovarian Sertoli-Leydig cell tumors, ocular medulloepithelioma). Eligibility: - Individuals who have been diagnosed with PPB and/or PPB-related tumors. - Close blood relatives (e.g., parents, siblings, grandparents) of individuals who have been diagnosed with PPB and/or PPB-related tumors. Design: - Interested participants can enroll or inquire about this study by calling 1-800-518-8474. - Participants will be asked to complete family history and medical history questionnaires. They will complete the questionnaire if they are at least 18 years of age, or another person will complete the questionnaire if the key family member is too young to do so on his or her own. - Participants will be asked to sign a medical record release form to allow researchers to examine detailed medical history information. - Participants may be asked to have a physical examination and imaging studies, provide blood and saliva samples, or provide tumor tissue from prior biopsies or cancer surgeries. - Annually, participants will update the family history and individual information questionnaires to document important changes in medical history, and will also update the medical record release form. Participants may be asked to provide additional cheek lining cells and/or blood samples, as well as tumor tissue from any new or planned biopsies or tumor surgeries. - Treatment will not be provided as part of this protocol....

Background: - Bronchiectasis is a disease characterized by airways that are inflamed, abnormally dilated, and chronically infected. Individuals with bronchiectasis have a history of chronic and recurring respiratory infections. Depending on the underlying cause, these infections may involve the entire respiratory tract, resulting in sinus, ear, and lung disease. - Bronchiectasis continues to be a significant problem in developing countries and in specific groups of individuals, particularly in people who have cystic fibrosis. Although treatments are available or under development for bronchiectasis related to cystic fibrosis, many of the disease-specific treatments may not be effective for bronchiectasis not related to cystic fibrosis. Objectives: - To study the natural history of bronchiectasis to identify inherited and immune factors that may explain why certain individuals have chronic recurring infections. Eligibility: - Individuals 5 years of age and older who have an established diagnosis of bronchiectasis or a history of chronic/recurring respiratory infections. - Direct family members (e.g., parents, siblings, children) of patients in the study may also be asked to participate. Design: - Potential participants will be screened with an initial clinic evaluation and full medical history, as well as a general quality of life and respiratory symptom questionnaire. - The following standard procedures may be done as part of the study: air sampling from the nose; imaging studies, which may include an x-ray or computed tomography (CT), lung function tests; and collection of samples of blood, urine, and sputum (phlegm or mucus). Other tests may be performed as required by the researchers, and will be explained to patients as needed. - Both patients and relatives (if asked to participate) will provide the following samples: blood or buccal (cheek swab) cells for genetic testing, sputum, and urine. - To prevent infections and potential disease progression, patients may receive standard medical care and treatment for bronchiectasis and related infections during this protocol.
