چکیده انگلیسی
We report an 11-month-old boy with acetazolamide-responsive epileptic apnea and inherited glycosylphosphatidylinositol (GPI)-anchor deficiency who presented with decreased serum alkaline phosphatase associated with compound PIGT mutations. The patient exhibited congenital anomalies, severe intellectual disability, and seizures, including epileptic apnea with epileptiform discharges from bilateral temporal areas. Brain magnetic resonance imaging revealed delayed myelination and progressive atrophy of the brainstem, cerebellum, and cerebrum. Whole-exome sequencing revealed compound heterozygous mutations in PIGT (c.250Â GÂ >Â T, p.Glu84X and c.1096Â GÂ >Â T, p.Gly366Trp), which encodes a subunit of the GPI transamidase complex. Flow cytometry revealed decreased expression of CD16 (a GPI anchor protein) on granulocytes, supporting the putative pathogenicity of the mutations. Phenobarbital, clonazepam, and potassium bromide decreased the frequency of tonic seizure and acetazolamide decreased epileptic apnea. To our knowledge, this is the first reported case of intractable seizures accompanied by epileptic apnea associated with GPI anchor deficiency and a compound PIGT mutation.
