Summary
This study details C-trigonocephaly syndrome, a rare condition associated with diaphragmatic hernia and severe intellectual disability. The findings highlight key clinical features and contribute to understanding this complex genetic disorder.
Area of Science:
- Medical Genetics
- Pediatrics
- Dysmorphology
Background:
- C-trigonocephaly syndrome is a rare genetic disorder characterized by a triangular skull shape.
- It is often associated with significant developmental abnormalities and congenital anomalies.
Observation:
- A 6-year-old girl with C-trigonocephaly syndrome presented with severe mental retardation and diaphragmatic hernia.
- Characteristic features included trigonocephaly, dysmorphic facial features (particularly intra-oral anomalies), low-set dysplastic ears, cardiac anomaly, and neonatal hypotonia.
Findings:
- Three cases of C-trigonocephaly are presented, including one with a fatal diaphragmatic hernia and another without.
- A review of 26 previously reported cases is included, expanding the known spectrum of this syndrome.
- The association between C-trigonocephaly syndrome and diaphragmatic hernia is further supported.
Implications:
- This report enhances the understanding of C-trigonocephaly syndrome's clinical presentation and genetic associations.
- It underscores the importance of recognizing and diagnosing C-trigonocephaly syndrome, especially when accompanied by diaphragmatic hernia.
- Further research into the genetic underpinnings and management strategies for C-trigonocephaly syndrome is warranted.
