Screening Red Flags
Findings on routine screening that may indicate genetic etiology
- Abnormal head shape not responding to repositioning
- Ridging along cranial sutures on palpation
- Facial asymmetry with additional anomalies
Exome / Genome Sequencing Indications
Clinical scenarios supporting ES/GS as a diagnostic approach
- Syndromic craniosynostosis (multi-suture or with extracranial features)
- Isolated craniosynostosis with negative FGFR/TWIST testing
- Cleft lip/palate with additional congenital anomalies
- Craniofacial anomalies with developmental delay
- Familial craniosynostosis or craniofacial anomalies
