Filter by:CoRDS, or the Coordination of Rare Diseases at Sanford, is based at Sanford Research in Sioux Falls, South Dakota. It provides researchers with a centralized, international patient registry for all rare diseases. This program allows patients and researchers to connect as easily as possible to help advance treatments and cures for rare diseases. The CoRDS team works with patient advocacy groups, individuals and researchers to help in the advancement of research in over 7,000 rare diseases. The registry is free for patients to enroll and researchers to access. Visit sanfordresearch.org/CoRDS to enroll.
Lowe syndrome is associated with mutations in the OCRL1 gene, which encodes OCRL1, a phosphatidylinositol-4, 5-bisphosphate (PtdIns(4, 5)P (2))5-phosphatase. PtdIns(4, 5)P2, a substrate of OCRL1, is an important signaling molecule within the cell. An abnormal rate of hemorrhagic events was found in a retrospective clinical survey, suggesting platelet dysfunction. The main objective of the study is to confirm the presence of platelet dysfunction in Lowe syndrome and to characterize this abnormality.
This study will explore conditions caused by the absence of certain genes on chromosome 11. These conditions include WAGR syndrome, which is characterized by a kidney tumor called Wilm s tumor, aniridia (absence of the iris of the eye), genital and urinary abnormalities, mental retardation, and possibly other symptoms. This study will examine how the genes on chromosome 11 affect people and whether the absence of specific genes is associated with specific symptoms. Healthy normal volunteers, people with isolated aniridia, and people with WAGR or another chromosome 11 gene deletion may be eligible for this study. Participants must be at least 6 years old. Parents of patients may also participate for genetic studies. Participants undergo some or all of the following procedures, depending on whether they are a child, adult, healthy volunteer or parent of a patient: - Medical history and physical examination, eye examination, blood, urine and saliva tests, electrocardiogram (EKG) and electroencephalogram (EEG) - X-rays, scans and other tests to measure body composition (fat, muscle and bone development and thickness) and MRI to examine the eyes and the brain and to measure abdominal fat - Ultrasound studies of the kidneys, ovaries and uterus (in females) and testes (in males) - Meal tests, food diaries and food preference tests - Questionnaires about eating and sleep habits, personality and character traits and responses to pain and injury - Neuropsychological tests - Tests of resting metabolic rate, energy expenditure and glucose (sugar) tolerance - Hot and cold sensitivity tests, vibration sensitivity test, cold tolerance test and smell identification test - Eye and hearing tests - Nerve conduction studies and study of sensory information conduction from peripheral nerves to the spinal cord and brain - Computer photography - Evaluation by sub-specialists (e.g., endocrinologist, ophthalmologist, physiatrist, neurologist or others) as indicated by the patient s medical history and test results
