Filter by:Background: We want to learn more about the relationship between the way families function and how children adapt to having a sibling with Duchenne muscular dystrophy (DMD). What we learn will help us design better interventions for families. Objective: - To learn more about how families with an individual with DMD function. - To learn how siblings adapt in families with an individual with DMD. Eligibility: - One parent and one child, age 13-18, from a family where another child has DMD. - The parent and the child must be able to read and write English. Design: - One parent from each family will complete a survey about how family members communicate and relate with each other. The parent will also answer questions about the behavior of the child without DMD. This survey will take you about 40 minutes to complete. - One child from each family, either a boy or a girl, will also complete a survey. This survey asks about how he/she views him/herself. It also asks about how he/she interacts with peers and family members and how he/she behaves. The survey also asks how satisfied he/she is with how his/her family functions. This survey takes about 30 minutes to finish.
Background: - Congenital malformations, sometimes called birth defects, occur because of a difference in early human development. There are many different types of congenital malformations, and some of these can be caused by changes in genetic material. Researchers are interested in studying individuals with these congenital malformations to better understand the causes and the effects of certain congenital malformations. Objectives: - To understand more about what causes congenital malformations that arise in early human development. - To learn if genetic causes can be found to explain why a person has a congenital malformation. Eligibility: - Individuals who have been diagnosed with a congenital malformation. Design: - Participants will be seen at the National Institutes of Health for a series of visits over 3 to 4 days. Participants will be asked to provide copies of past medical records and test results for review, and will be asked questions about pregnancy/prenatal history, birth, newborn, medical, developmental, and family history. - Parents or siblings of participants may also be asked to provide information for research purposes. - Participants may have additional medical evaluations as part of this study, including any of the following tests: - Physical examinations - Other consultations as clinically indicated - Blood samples for genetic testing - Tissue biopsy for genetic testing - Photographs of affected areas, such as front and side views of the face and other body parts that may be involved in a congenital malformation, like the hands and feet. - Other tests as indicated by a specific malformation, such as organ ultrasounds. - No additional invasive testing, testing requiring sedation, or testing involving radiation is planned for this protocol. These tests, if performed, would involve a separate consent....
The general area of research in which this project has been designed is that of retinal degeneration related to mutations in the ABCR gene, responsible of Stargardt disease/fundus flavimaculatus retinal dystrophy (STD/FF). STG/FF is one of the major causes of vision impairment in the young age. STG/FF originates typically from the dysfunction and loss of cone and rod photoreceptors, developing through a photo-oxidative mechanism. The major disease locus is the central retina, i.e. the macula, whose neurons have the highest density and underlie critical functions such as visual acuity, color vision and contrast sensitivity. There is currently no cure for STG/FF. Recent experimental findings indicate that Saffron, derived from the pistils of Crocus Sativus, may have a role as a retinal neuro-protectant against oxidative damage. The stigmata of Crocus sativus contain biologically high concentrations of chemical compounds including crocin, crocetin, whose multiple C=C bonds provide the antioxidant potential. In addition it is well known that this compound is safe and free of adverse side effects. The aim of this research is to investigate the influence of short-term Saffron supplementation on retinal function in STG/FF patients carrying ABCR mutations. The macular cone-mediated electroretinogram (ERG) in response to high-frequency flicker (focal flicker ERG) will be employed as the main outcome variable. Secondary outcome variable will be the psychophysical cone system recovery after bleaching.
The purposes of this study are to identify the genes responsible for several inherited disorders commonly seen in the Amish and Mennonite populations and learn more about the natural history (medical problems that develop over time) of these disorders. In addition, researchers will establish a computer database containing Amish genealogies, derived largely from the community s extensive records of births, marriages, deaths, etc., that will help construct pedigrees (family trees) for genetic study. The Amish and Mennonite peoples have a high rate of intermarriage within their individual communities, with a resulting high incidence of inherited disorders. Many of these disorders, such as cartilage-hair hypoplasia, Ellis-van Creveld syndrome, and others, are rarely seen outside these communities. New research using state-of-the-art methodologies in genetics will add to current knowledge about the causes and symptoms of these disorders that will eventually aid in their diagnosis and medical management. Patients with inherited disorders that occur frequently in the Amish and Mennonite populations and their family members may be eligible for this study. Individuals from both within and outside these communities may enroll. Participants will be evaluated with a review of their medical records and their personal and family medical history and a brief physical examination. A small tissue sample will be collected for genetic studies. This will be either a blood sample (3 teaspoons from adults and 1 to 3 teaspoons from children, depending on their size) or a mouth swab (cells removed from inside the cheek by gentle brushing). Some participants may undergo additional procedures, such as diagnostic X-rays, brain scans, echocardiogram (heart ultrasound) or other studies. If genetic testing shows a gene change (mutation), the participant will be notified to that effect in writing and offered counseling in their home regarding the test results and their implications....
Umbilical cord blood is used as a source of hematopoietic stem cells for bone marrow reconstitution in patients who would be potential candidates for a bone marrow transplant from an unrelated marrow donor. The outcome of transplantation is obtained to assess cord blood myeloid and platelet engraftment, transplant related mortality, overall survival, graft vs. host disease and, for patients with leukemia, lymphoma or myelodysplasia, relapse.
