NCT00367796
This study will try to find the gene changes responsible for the birth defects in craniosynostosis, Philadelphia type. Craniosynostosis syndromes are a group of conditions that result from closure of one or more of the fibrous joints between the bones of the skull before brain growth is complete. Because of the premature closure, the brain is not able to grow in its natural shape; instead, it compensates with growth in areas of the skull where the joints have not yet closed. The defects in raniosynostosis, Philadelphia type, include skull malformations and webbing of the fingers and toes. Gene changes known to be involved in other craniosynostosis syndromes have not been found in the Philadelphia type syndrome. Therefore, finding the genetic basis of this disorder will provide important new information regarding craniofacial and limb development. This study includes members of a single large family affected with craniosynostosis, Philadelphia type. Participants have 1 to 2 teaspoons of blood drawn for genetic studies. A second blood sample may be requested for further research. Some blood may be used to establish a cell line for later studies. This involves growing the white blood cells from the blood sample. The cells can be kept in the laboratory to make more DNA or can be frozen for later use in craniosynostosis studies. Patients may also have their medical records reviewed.
NCT01710332
A preliminary study to determine the safety and efficacy of intravitreal aflibercept injection in patients with persistent central serous chorioretinopathy.
NCT01982591
This research trial studies heavy metal exposure in predicting peripheral neuropathy in patients with stage I-III breast cancer undergoing chemotherapy. Studying samples of blood and urine in the laboratory for heavy metal exposure from patients receiving chemotherapy may help doctors find out whether side effects from chemotherapy are related to heavy metal exposure.
