Background: Turner Syndrome, galactosemia, and premature ovarian insufficiency are all conditions that may make it very hard or impossible for a person to become pregnant and have their own child. Researchers want to learn more about why this happens and if freezing Gonadal tissue allows for fertility preservation. Objective: To find out why people with certain conditions have can have premature ovarian insufficiency (POI or early menopause) and individuals with variations in sex characteristics have trouble getting pregnant and if freezing the gonads tissue from them will help to have their own child in the future. Eligibility: Individuals aged 2-21 who have Turner Syndrome or galactosemia. Also, females aged 13-21 with premature ovarian insufficiency, individuals with variations in sex characteristics, and individuals 2-35 receiving high-risk gonadotoxic therapy Design: Participants will be screened with a medical history. Participants may have a physical exam and blood tests. Their body measurements may be taken. These include weight, height, arm span, skin fold, and sitting height. They may fill out surveys about their quality of life, body image, and health. Participants may have a transabdominal pelvic ultrasound. A probe will be placed on their belly and will take pictures of the organs in the pelvis. They may have a transvaginal pelvic ultrasound performed while asleep in the operating room if needed. Participants may have surgery to remove an gonads and skin biopsy. The removed tissue will be frozen and stored. The tissue will have to be stored for many years. NIH will pay to store the tissue for 1 year. After that, participants will have to pay for storage. A piece of the gonads (no more than 20%) will be used for research Travel, lodging and meals for participants traveling greater than 50 miles will be reimbursed based off the government rate. Local participants will not be reimbursed. Participants will have a checkup 6 weeks after surgery one or more follow-up visits 6-18 months after surgery. They may have phone follow-up every 12-24 months after surgery. Participation will last 30 years.

Background: A person s tumor is studied for mutations. When cells are found that can attack the mutation in a person s tumor, the genes from those cells are studied to find the parts that make the attack possible. White blood cells are then taken from the person s body, and the gene transfer occurs in a laboratory. A type of virus is used to transfer the genes that make those white blood cells able to attack the mutation in the tumor. The gene transfer therapy is the return of those white blood cells back to the person. Objective: To see if gene transfer therapy of white blood cells can shrink tumors. Eligibility: People with certain metastatic cancer for which standard treatments have not worked. Design: Participants may complete screening under another protocol. Screening includes: - Getting tumor cells from a previous procedure - Medical history - Physical exam - Scans - Blood, urine, heart, and lung tests The study has 8 stages: 1. Screening tests repeated over 1-2 weeks. Participants will have leukapheresis: Blood is removed by a needle in one arm. A machine removes white blood cells. The rest of the blood is returned by a needle in the other arm. 2. Care at home over approximately 12 weeks. 3. Stopping therapy for 4-6 weeks while their cells are changed in a lab. 4.

This study will determine the biochemical and genetic causes of inherited immune diseases affecting lymphocyte homeostasis. Lymphocytes are a type of white blood cell that fights infections. Normally, the body keeps a precise balance in which lymphocyte growth is matched by lymphocyte death. People with constantly enlarged lymph nodes or spleen, along with autoimmune disease, immunodeficiency, lymphoma, or other immune problems affecting lymphocytes may have an abnormality of the immune system in the cell growth and cell death processes that regulate lymphocyte homeostasis. Patients who have, or are suspected of having, an inherited lymphocyte homeostasis or programmed cell death susceptibility syndrome may be eligible for this study. Relatives of patients are also included. Participants' (patients and relatives) medical records are reviewed and blood samples are drawn for studies to identify genes involved in immune disorders. Tissues that have been removed from patients for medical reasons, such as biopsied tissues, may be examined for tissue and DNA studies. Relatives are studied to determine if some of them may have a very mild form of lymphocyte homeostasis disorder. Patients who have an immune problem that the researchers wish to study further will be invited to donate additional blood samples at irregular intervals (at least once a year) and to provide an update of their medical records at the same time.

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

PTH1R is predominantly expressed in the kidneys and bone and growth-plate chondrocytes. Individuals with JMC develop severe growth impairment resulting in significant short stature, scoliosis, frequent fractures, bone pain, mineral-ion abnormalities (typically hypercalcemia and hypercalciuria), hypertension, and chronic kidney disease due to nephrocalcinosis and nephrolithiasis. Children often undergo multiple surgeries for skeletal fractures and deformities; mobility is commonly impaired, usually requiring assistive devices for ambulation. Other complications may include premature closure of cranial sutures and cranial nerve compressions with the potential for vision and/or hearing loss [1-3]. Physical function impairment and the need for complication-related operations have profound deleterious effects on quality of life in individuals with JMC. There are currently no approved therapies for JMC, and novel therapies are critically needed to prevent irreversible disease complications and improve patient quality of life. The inventors of the drug, parathyroid hormone inverse agonist (PTH-IA), have considerable expertise in both the basic and clinical aspects of PTH/PTHrP receptor molecular biology and pharmacology. They reported the first PTH1R JMC mutations (including the H223R mutation) over 20 years ago and identified certain PTH antagonist ligands that function as inverse agonists on the PTH1R JMC mutant receptors [2, 4]. These ligands suppress the mutant receptor s elevated basal rates of cAMP signalling, as assessed in cultured cells and animal models. In vivo studies confirm that inverse agonist ligands may be effective in treating JMC. This study involves the use of PTH-IA, a 30-amino acid PTH inverse agonist ligand with the amino acid sequence [Leu11,dTrp12,Trp23,Tyr36]-PTHrP(7-36)NH2. We hypothesize that PTH-IA will be a safe and effective treatment for individuals with JMC.

Background: Premature ovarian insufficiency (POI) is a condition in which women under the age of 40 years have absent or irregular menstrual cycles. POI can cause infertility, signs of menopause, osteoporosis, and other symptoms. Hormone replacement therapy (HRT) is a treatment that gives women extra hormones, such as estrogen and progesterone. HRT works well in adult women. Researchers want to find the most effective doses and regimens for adolescents. Objective: To monitor the effects of HRT on adolescents with POI. Eligibility: Female adolescents aged 11 to 19 years diagnosed with POI. Healthy volunteers are also needed. Design: All participants will have clinic visits every 6 months for 2 years. Each visit may last 2 days. Each visit may include: Blood and urine tests. A test of their heart function. A test to measure the stiffness of their blood vessels. Participants will lie flat with a blood pressure cuff on a leg and a meter on the neck while the cuff inflates. A test of their grip strength. Participants will squeeze a handheld device as hard as they can. Two scans to measure bone density. For one, participants will lie on a table while a scanner passes along their body. For the other, participants will sit in a chair and insert their forearm, then their lower leg, into a scanner. A test to measure skin pigmentation. Participants' skin will be touched lightly with a device. An optional visual exam of the vagina. Some vaginal fluid may also be collected with a cotton swab/cytobrush. Participants with POI will receive HRT. They will be given estrogen patches and progesterone pills.
