Pyridox(am)ine-5'-phosphate oxidase deficiency:A case report and literature review
The clinical data of a child with Pyridox(am)ine-5'-phosphate oxidase(PNPO)deficiency admitted to the First Affiliated Hospital of Army Medical University in August 2022 were retrospectively analyzed,and relevant literature was retrieved and reviewed.The child was a male with a gestational age of 34 weeks 4 days,and presented with refractory convulsion with myoclonic seizures in less than 24 hours after birth,with the electroencephalogram showing a violently inhibitory pattern,and the presence of a compound heterozygous variant of the PNPO gene was confirmed by genetic analysis:c.448_451del paternal origin and c.558_561del maternal origin.For early neonatal seizures with poor outcome on conventional antiepileptic therapy,the possibility of the disease should be considered,and confirmation of the diagnosis relies on genetic testing.
