Ocular and facial maldevelopment: the role of neural crest

Area of Science:

• Developmental biology
• Ophthalmology
• Genetics

Background:

• Neural crest cells are crucial for craniofacial and ocular development.
• Disruptions in neural crest cell migration can lead to complex congenital abnormalities.
• Understanding these developmental pathways is key to diagnosing and managing affected individuals.

Purpose of the Study:

• To describe a spectrum of clinical abnormalities in three children affecting ocular and non-ocular tissues.
• To explain these conditions as disorders of neural crest migration.
• To explore the underlying mechanisms of combined facial skeleton and eye malformations and classify them as neurocristopathies.

Main Methods:

• Clinical case description and analysis.
• Review of ocular embryology principles.
• Discussion of neurocristopathies and their implications.

Main Results:

• Three children presented with a range of eye and systemic abnormalities.
• These abnormalities are consistent with disruptions in neural crest cell development.
• The findings support the classification of these conditions as neurocristopathies.

Conclusions:

• The described spectrum of abnormalities is best explained by disorders of neural crest migration.
• Identification of these conditions necessitates a thorough search for other systemic developmental disorders.
• These cases highlight the importance of considering neurocristopathies in patients with combined craniofacial and ocular malformations.
