Neurological manifestations are among the most serious for paediatric patients with hypophosphatasia. These neurological manifestations can, for example, be:
- Vitamin B6-related seizures
- Epileptic encephalopathy
- Craniosynostosis with associated complications such as increased intracranial pressure, optic nerve damage and/or papilloedema
Beaten copper appearance and craniosynostosis

Impaired growth can also lead to neurological consultation. Children with hypophosphatasia often exhibit delayed motor development or completely missed motor milestones.
In infants, vitamin B6-related seizures are an poor prognostic sign and are related to mortality in most cases.
