Filter by:The My Retina Tracker® Registry is sponsored by the Foundation Fighting Blindness and is for people affected by one of the rare inherited retinal degenerative diseases studied by the Foundation. It is a patient-initiated registry accessible via a secure on-line portal at www.MyRetinaTracker.org. Affected individuals who register are guided to create a profile that captures their perspective on their retinal disease and its progress; family history; genetic testing results; preventive measures; general health and interest in participation in research studies. The participants may also choose to ask their clinician to add clinical measurements and results at each clinical visit. Participants are urged to update the information regularly to create longitudinal records of their disease, from their own perspective, and their clinical progress. The overall goals of the Registry are: to better understand the diversity within the inherited retinal degenerative diseases; to understand the prevalence of the different diseases and gene variants; to assist in the establishment of genotype-phenotype relationships; to help understand the natural history of the diseases; to help accelerate research and development of clinical trials for treatments; and to provide a tool to investigators that can assist with recruitment for research studies and clinical trials.
Bardet-Biedl Syndrome (BBS) is a rare genetic disorder associated with a vast array of symptoms. The features of BBS are highly variable, even between siblings, making long-term follow-up and centralization of information vital to better understanding this complex disease and designing effective treatments. Marshfield Clinic has developed the Clinical Registry Investigating Bardet-Biedl Syndrome (CRIBBS) to gather comprehensive health information from patients diagnosed with BBS in a single repository. This information will be used to inform patients, families, and physicians about the complex features of BBS and will serve as a platform for researchers to develop effective and targeted treatment strategies for patients with BBS. CRIBBS is a web-based, confidential database and the privacy of patients enrolled in the registry will always be respected. Information maintained in the database will be identifiable only by an assigned study identification number, not by name. The registry strictly complies with HIPAA regulations. CRIBBS participants may be contacted periodically with information regarding clinical trials or research studies, but participation is entirely voluntary. CRIBBS will bring together complex genetic and clinical information from BBS patients to accelerate research into effective treatments, attract additional researchers, and make it easier for researchers to identify patients and find funding for innovative studies.
In 2005, The University of Alabama at Birmingham established a NIDDK-funded, interdisciplinary center of excellence in PKD-related research, with specific emphasis on recessive PKD. In the previous Core Center award period, we developed a Core Resource to capture clinical and mutational data for ARPKD patients ("Core A: ARPKD Clinical and Genetic Resource", NCT00575705). However, studies in the last several years have demonstrated that ARPKD and other single gene disorders characterized by renal cystic disease and extra-renal phenotypes share numerous pathogenic features. In the current competitively- renewed Center, we have expanded this Core resource to include other hepato/renal fibrocystic diseases. Goals for the Core A: The Hepato/Renal Fibrocystic Diseases Translational Resource are: 1. - Clinical Database: • Expand our comprehensive Clinical Database to include information from all patients who meet the inclusion criteria for hepato/renal fibrocystic diseases. 2. - Mutational Database: - Test children with ARPKD and other hepato/renal fibrocystic disease to identify genetic mutations, establish a DNA bank for patients with hepato/renal fibrocystic diseases and develop a Mutational Database. This Database will be capable of linking clinical and mutational information via a unique identifier in a searchable format to facilitate genetic research (e.g. genotype-phenotype correlations, new disease gene studies, and modifier gene studies), translational studies, and clinical trials. 3- Tissue Resource: - Much of the research that is performed on diseases of the kidney, including recessive genetic diseases, requires human tissue from both affected as well as non-affected (controls) individuals. In this Core Resource, we are establishing an independent tissue resource which would supply investigators throughout North America with samples of hepato/renal fibrocystic disease affected tissues for studies of these disorders. 4- Educational Resource: - Expand our multi-media, web-based resource to provide a reliable up-to-date, and comprehensive informational resource for ARPKD and Hepato/Renal Diseases families, their physicians, and genetic counselors. All the information regarding participation in "Core A: The Hepato/Renal Fibrocystic Diseases Translational Resource" is available at: http://www.arpkdstudies.uab.edu/.
This study is based on the study of the natural history of a rare disorder: the Bardet-Biedl syndrome (BBS) (which is associated with retinitis pigmentosa, polydactyly, cognitive impairment, obesity, and kidney failure). The clinical, biological, and radiological features of adult patients are studied. In parallel, a molecular study is performed on the known genes to date (8 genes from BBS1 to BBS8) and to identify new genes involved. The parts of the study are combined in a phenotype-genotype correlation study.
This study will evaluate patients with a rare inherited condition called Bardet-Biedl syndrome . The purpose of the study is to learn more about the genetics and clinical characteristics of this disorder. Patients may have the following problems: polydactyly (extra fingers and toes); retinal dystrophy (changes in the retina that may lead to vision problems, including blindness); obesity and diabetes (overweight and high blood sugar due to failure of body organs to respond to insulin); cognitive dysfunction (difficulties with learning and understanding); hypogenitalism (decreased functioning of the ovaries in women and the testes in men); kidney anomalies (changes in the structure or function of the kidneys); heart disease; and hepatic fibrosis (liver disease). Patients with Bardet-Biedl syndrome may be eligible for this study. First-degree relatives will also be enrolled for certain tests and procedures. Candidates are screened with a review of their medical records, laboratory tests, and x-rays. Patients in this study undergo the following tests and procedures: - Medical and family history and physical examination, including body measurements. - Blood tests to evaluation kidney, liver, heart, and hormonal function, and for genetic studies and other research purposes. - Dual emission x-ray absorptiometry (DEXA) scan to measure the amount of total body fat. For this test, the subject lies on a table for scanning with low-dose X-rays. - Computed tomography (in adults) of the abdomen to measure abdominal fat. CT uses a small amount of radiation to obtain images of internal body structures. - Magnetic resonance imaging (in children) of the abdomen to measure abdominal fat. MRI uses a magnetic field and radio waves to obtain images of internal body structures. - Oral glucose tolerance tests to measure blood glucose and insulin levels. For this test, the patient drinks a glucose (sugar) solution. Blood samples are drawn through an IV catheter before the test begins and at 1, 2, and 3 hours after drinking the solution. - Complete eye examination to look for retinal changes and to assess vision, and, if medically needed, an examination of the ear, nose, and throat to check for hearing and breathing abnormalities. - Tests of learning ability in patients over 5 years of age. For younger patients, a parent is asked about the child's development. - Ultrasound study of the ovaries and uterus in females and of the testes in males. - Photographs of the face, hands, feet, body, and genitalia, if the patient agrees. - Meeting with investigators and a genetic counselor for review of test findings when the studies are completed. Relatives of patients have a complete medical and family history and physical examination. Blood is drawn for assessment of kidney, liver, heart, and hormonal function and for genetic study and other research purposes. Relatives over 5 years of age may have tests of learning ability and cognition. For younger patients, a parent is asked about the child's development. Relatives meet with investigators and a genetic counselor for review of test findings when the studies are completed.
