Craniofrontonasal dysplasia in a three-generation kindred
Journal of Craniofacial Genetics and Developmental Biology
|January 1, 1982
Summary
Craniofrontonasal dysplasia, a rare condition involving facial and skull malformations, was studied in a three-generation family. The inheritance pattern remains unclear, suggesting potential genetic or metabolic factors influencing recurrence risk.
Area of Science:
- Medical Genetics
- Developmental Biology
- Clinical Dysmorphology
Background:
- Frontonasal dysplasia and craniosynostosis are typically isolated developmental defects.
- Cohen described a syndrome combining these, termed craniofrontonasal dysplasia.
Observation:
- A three-generation family exhibited variable frontonasal dysplasia and craniosynostosis.
- Five individuals (four female, one male) were affected.
Findings:
- The inheritance pattern in this family is indeterminate.
- Possible modes include autosomal dominant with sex-influenced expression or X-linked dominant inheritance.
- Metabolic interference is also considered.
Implications:
- This family represents a distinct subpopulation with craniofrontonasal dysplasia.
- Patients with this familial pattern may have a higher risk of recurrence.
- Further research into the genetic and molecular mechanisms is warranted.
