objective: intractable epilepsy is a serious neurologic problem with different etiologies. decreased levels of pyridoxal phosphate in central spinal fluid level of patients with intractable epilepsy due to pyridoxine dependency epilepsy were reported. the aim of this study was to compare plasma pyridoxal 5´-phosphate level in patients with intractable and controlled epilepsy. materials & ...
Pyridoxine-dependent epilepsy presents early in life, even in utero. It is usually refractory to conventional antiepileptic medications and responds only to lifelong pyridoxine supplementation. Seizures are usually generalized tonic clonic. We report a 3-year-old child that was born prematurely at 25 weeks of gestation. He presented with abnormal movements in the second month of life. At 10 mon...
Pyridoxine-dependent epilepsy (PDE) is a rare autosomal recessive enzyme defect in the vitamin B6 metabolism characterized by intractable seizures which are usually resistant to all antiepileptic drugs but respond to pharmacological doses of pyridoxine. We present the clinical and molecular genetic findings of two patients with c.1597_1597delG mutations in ALDH7A1 gene. There are different clin...
A 2-day-old male neonate became increasingly irritable and developed repetitive twitching in the eyelids, face, and limbs around 24 h of life. He was the full-term product of nonconsanguineous parents following a normal pregnancy and uneventful spontaneous vaginal delivery. Investigations for infectious etiologies including blood and urine cultures as well as cerebrospinal fl uid analysis were ...

Pyridoxine-dependent epilepsy is a rare, autosomal recessive, treatable cause of neonatal seizures. Genetic testing can confirm mutations in the ALDH7A1 gene, which encodes antiquitin. To avoid delays in initiating treatment while awaiting confirmatory genetic testing, it is recommended that all neonates with unexplained seizures should receive trial of intravenous (IV) pyridoxine to assess for...
Pyridoxine-dependent epilepsy was recently shown to be due to mutations in the ALDH7A1 gene, which encodes antiquitin, an enzyme that catalyses the nicotinamide adenine dinucleotide-dependent dehydrogenation of l-alpha-aminoadipic semialdehyde/L-Delta1-piperideine 6-carboxylate. However, whilst this is a highly treatable disorder, there is general uncertainty about when to consider this diagnos...
OBJECTIVE To investigate the role of intragenic deletions of ALDH7A1 in patients with clinical and biochemical evidence of pyridoxine-dependent epilepsy but only a single identifiable mutation in ALDH7A1. METHODS We designed a custom oligonucleotide array with high-density probe coverage across the ALDH7A1 gene. We performed array comparative genomic hybridization in 6 patients with clinical ...
