Study of Clinical and Molecular Manifestations of Genetic Disorders
An observational study of Hereditary Diseases, run by National Human Genome Research Institute (NHGRI) at 1 site in United States.
Trial summary
This study will investigate the cause and natural history (medical problems that appear over time) of certain genetic disorders. It will also try to locate the abnormal genes responsible for these conditions and eventually develop tests to predict who is likely to be affected and to what degree. Read more about this study

About this study
Official title: Clinical and Molecular Manifestations of Six Categories of Genetic Disorders
This study will investigate the cause and natural history (medical problems that appear over time) of certain genetic disorders. It will also try to locate the abnormal genes responsible for these conditions and eventually develop tests to predict who is likely to be affected and to what degree.
Patients with known or suspected genetic disorders in certain categories, such as those involving chromosomal or metabolic abnormalities, immune system or blood disorders, abnormal growth, benign tumors, and others may be eligible for this study. Participants will be interviewed by specialists in genetics about their condition and family history. They may also be asked to have a physical examination and certain tests needed for study of the specific individual's condition. These may include collection of blood samples (up to 3 tablespoons); imaging studies, such as computerized tomography (CT), magnetic resonance imaging (MRI), ultrasound and echocardiography; skin biopsy (removal of a small sample of skin tissue under local anesthetic), and other procedures. DNA testing may reveal the genetic abnormality responsible for the disorder. Participants who so wish will have an opportunity to talk with experts about the health implications of the test results.
This study may provide information that will lead to improved treatment or management of these inherited disorders, as well as more effective genetic counseling for families.
Read the detailed description
Individuals and their families affected by disorders with a potentially genetic basis within six broad categories will be evaluated over time to characterize the natural and clinical history of various specific disorders. Medical and laboratory evaluations will be completed to identify areas of management concern that have not been previously described. Further protocols will be developed addressing specific disorders once a number of affected individuals have been investigated and is sufficient to query various aspects of those disorders. Issues for both diagnosis and medical management of those affected with certain genetic disorders will be collated and addressed within a national consensus conference format. In addition, phenotype to genotype correlation will be established to further understanding of specific molecular alterations on phenotypic expression. This broad-based protocol will also facilitate the training of fellows in medical genetics, graduate and post graduate training in genetics and genetic counseling.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This study will investigate the cause and natural history (medical problems that appear over time) of certain genetic disorders. It will also try to locate the abnormal genes responsible for these conditions and eventually develop tests to predict who is likely to be affected and to what degree.
Patients with known or suspected genetic disorders in certain categories, such as those involving chromosomal or metabolic abnormalities, immune system or blood disorders, abnormal growth, benign tumors, and others may be eligible for this study.

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Mar 2008.
