It is an observational (non-phase) study and has been completed.
The summary above is a plain-language rendering of the official record. The original English title is shown for reference.
Criteria are reproduced from the ClinicalTrials.gov record in the original English. Only the trial team can determine eligibility.
* INCLUSION CRITERIA: * Individuals and their family members will be offered enrollment if they have an established or suspected diagnosis of Marfan, Stickler, or Ehlers-Danlos syndrome, or Overlap connective tissue disorder. * Determination of eligibility will be made by review of prior records. * In some cases, a screening evaluation to establish the diagnosis may be performed subjects may be excluded from further participation if the diagnosis is ruled out. Cytogenetic analysis may be necessary to rule out a chromosomal abnormality that has overlapping features with HDCT. * Clinical inclusion criteria require: personal or family history of one or more of the following features in a pattern suggestive of a heritable connective tissue disorder: Marfanoid body habitus, aortic dilatation and/or dissection, ectopia lentis, detached retina, vitreous degeneration and/or early onset high myopia, posterior cleft palate, joint laxity and/or dislocation, premature osteoarthritis, skin fragility, striae, easy bruising and/or hyperextensibile skin, pectus excavatum or carinatum, scoliosis, spondylolisthesis and/or dural ectasia, Chiari I Malformation, high frequency sensorineural hearing loss, fibromuscular dysplasia of arteries, aneurysms. EXCLUSION CRITERIA: * The only exclusion criterion is inability to provide informed consent, or the absence of a guardian who is authorized to provide informed consent in the case of minor subjects. * There will be no exclusion based upon age, gender, ethnicity, socioeconomic status, or any other factor except ability to provide informed consent. * Pregnant and nursing women may be limited in their participation in some aspects of the study (e.g. ionizing radiation exposure or MRI) during the time that they are pregnant or nursing.
