Network Of Clinical Research Studies On Craniosynostosis, Skull Malformations With Premature Fusion Of Skull Bones

Sponsor: Icahn School of Medicine at Mount Sinai

View on ClinicalTrials.gov

Summary

Craniosynostosis (CS) is a common malformation occurring in \~4 per 10,000 live births in which the sutures between skull bones close too early, causing long-term problems with brain and skull growth. Infants with CS typically require extensive surgical treatment and may experience many perioperative complications, including hemorrhage and re-synostosis. Even with successful surgery, children can experience developmental and learning disabilities or vision problems. Most often, CS appears as isolated nonsyndromic CS (NSC). Of the several subtypes of CS, unilateral or bilateral fusion of the coronal suture is the second most common form of CS accounting for 20-30% of all NSC cases. The etiology of coronal NSC (cNSC) is not well understood, although the published literature suggests that it is a multifactorial condition. About 5-14% of coronal craniosynostosis patients have a positive family history, with a specific genetic etiology identified in \>25% of cNSC cases, suggesting a strong genetic component in the pathogenesis of this birth defect. The causes for cNSC and its phenotypic heterogeneity remain largely unknown. An international team of investigators will generate large genomic and gene expression datasets on samples from patients with cNSC. State-of-the-art imaging, genetic, and developmental and systems biology approaches will be used to quantitatively model novel pathways and networks involved in the development of cNSC. Novel variant-, gene- and network-level analyses will be performed on the genomic data obtained from cNSC cases, their relatives, and controls to identify novel variants and genetic regions associated with cNCS. Quantitative, analytical, and functional validations of these predictions will provide insights into the etiology and possible therapeutic targets for CS and potentially other bone-related disorders.

Interventions

OTHER

Craniosynostosis Network Environmental Survey

Questionnaire is administered to the mothers of affected participants regarding medical history and environmental exposures during pregnancy, delivery, and neonatal period. Optional.

OTHER

2D/3D Photography

Full frontal and lateral face and other parts of the body may be taken for dysmorphic assessment. There is the risk of identification and loss of confidentiality. Optional.

PROCEDURE

Buccal Swab Cell Sampling

One or more swabs, like a Q-tip (for children), or saliva collection kit (for adults) will be used to collect buccal cells. With a swab, they will brush the inside of the mouth several times. With saliva collection kit, they will collect their saliva by spitting into a container several times using a commercially available saliva collection kit. Required.

PROCEDURE

Blood sampling

Venipuncture so that one teaspoon to tablespoons (1-20 ml.) of blood is collected. The volume drawn will be dependent on the age and size of the child. Minimal amounts may be required for DNA, but to establish a lymphoblastoid or iPS cell line at least 3 to 10 ml will be required independent of age. In the case of an infant, if 3 to 10 ml cannot be obtained, then a lymphoblastoid or iPS cell line will not be created. Optional.

PROCEDURE

Skin Biopsy

For those who do not undergo surgery or the skin removal is not considered part of the surgical procedure. After proper cleaning, a piece of skin the size of a pencil eraser (about 4 mm or 1/8 inch in diameter) will be removed (using a circular blade or scalpel) from the arm (inside of arm or forearm in a spot that is as unnoticeable as possible). This area will be covered with a Band-Aid. No stitches are usually required. A crust will form and eventually fall off. Optional.

PROCEDURE

Tissues from a Clinically Indicated Procedure

In some instances when there is discarded tissues and specimens (including skin and bone at the time of reconstructive craniofacial surgery), they will be collected by making arrangements with their physicians. Some of these tissues will be used to generate cell lines. Optional.

PROCEDURE

Pre-operative CT Scan Image Files.

Optional for those who had a previous CT scan for a prior traumatic event.
