Researchers from participating institutions use the database to search for and invite patients or healthy volunteers who meet their study criteria to participate. The lifespan of the individuals varies based on the extent of the disease. There are two main types of clinical studies: People participate in clinical trials for a variety of reasons.

Cognitive impairment - coarse facies - heart defects - obesity CHOPS syndrome is a disorder involving multiple abnormalities that are present from birth (congenital). You can review and change the way we collect information below. What causes Cornelia de Lange syndrome? The researchers have shown that CHOPS syndrome is a de novo condition-being caused by a new mutation arising in a single egg or sperm that went on to form the affected child, but not present in the patients parents.
