Official Title: Clinical Study of Muenke Syndrome (FGFR3-Related Craniosynostosis)

Brief Summary:

This study will explore the range and type of medical and developmental problems in patients with Muenke syndrome, a condition that results when one or more of the suture between the bones of the skull close before birth. Because of the premature closure, the skull is not able to grow in its natural shape; instead, it compensates with growth in areas of the skull where the sutures have not yet closed. This can result in an abnormally shaped head, wide-set eyes, and flattened cheekbones. Patients may also have an enlarged head, abnormalities of the hands or feet, and hearing loss.

The fibroblast growth factor receptor 3 (FGFR3) gene, which is involved in the development and maintenance of bone tissue, plays a role in Muenke syndrome. In some cases, the FGFR3 mutation is inherited from a parent with Muenke syndrome; in other cases, where there is no family history of the disorder, the mutation occurs anew. A better understanding of this gene may lead researchers to develop better treatments and genetic counseling for people affected by Muenke syndrome.

Patients with Muenke syndrome and their blood relatives may be eligible for this study. Family members with confirmed Muenke syndrome will have genetic counseling, and patients undergo the following tests and procedures:

  • Review of medical records and test results.
  • Questionnaires about the patient's prenatal, birth, newborn, and past medical history; family history; growth and development; medications; and current therapies.
  • Physical, neurological, ear, nose and throat, dental, and eye examinations.
  • Neuropsychological testing to assess cognitive thinking abilities.
