Pipecolic Acid as a Diagnostic Marker of Pyridoxine-Dependent Epilepsy
Neuropediatrics, 2005 Pyridoxine-dependent epilepsy, although described some decades ago, may still be an underdiagnosed disorder. We have recently described isolated pipecolic acid elevations in the plasma and/or CSF of three patients with pyridoxine-dependent epilepsy with an intriguing inverse correlation to the oral intake of pyridoxine.

Current Treatment and Management of Pyridoxine-Dependent Epilepsy
Current Treatment Options in Neurology, 2015 Pyridoxine-dependent epilepsy (PDE) is a rare autosomal recessive disorder and is considered as a prototypical form of metabolic epilepsy. Characterized by recurrent seizures in the prenatal, neonatal, and/or postnatal periods that are resistant to conventional anti-epileptic drugs, PDE is responsive to pharmacological dosages of pyridoxine. Presently,

Pyridoxine-dependent epilepsy: report on three families with neuropathology
Metabolic Brain Disease, 2016Pyridoxine-dependent epilepsy (PDE) is a pharmacoresistant epileptogenic encephalopathy controlled by pyridoxine supplementation at pharmacological doses. Despite supplementation, the long-term outcome is often poor possibly because of recurrent seizures and developmental structural brain abnormalities.

Gene sleuthing in pyridoxine-dependent epilepsy
Neurology, 2015Epilepsies caused by inborn errors of metabolism consist of a broad range of diseases, typically with early life onset and often associated with progressive encephalopathy. Early recognition and targeted therapy are key to improved outcomes in several metabolic epilepsies, including those related to the pyridoxal vitamer dependencies.

Timing of therapy and neurodevelopmental outcomes in 18 families with pyridoxine-dependent epilepsy [PDF]
Molecular Genetics and Metabolism, 2022 BACKGROUND: Seventy-five percent of patients with pyridoxine-dependent epilepsy due to α-aminoadipic semialdehyde dehydrogenase deficiency (PDE-ALDH7A1) suffer intellectual developmental disability despite pyridoxine treatment.

Congenital cataract in a child with pyridoxine-dependent epilepsy
Journal of American Association for Pediatric Ophthalmology and Strabismus, 2013Pyridoxine-dependent epilepsy (PDE) is a cause of neonatal epileptic encephalopathy not previously known to cause ophthalmic disease. We describe the novel observation of a 5-year-old girl with pyridoxine-dependent epilepsy and bilateral cataracts. PDE is the result of mutations in the ALDH7A1 gene encoding antiquitin, an enzyme protective against ...

This chapter focuses on disorders due to mitochondrial respiratory chain (MRC) dysfunction and use the collective term mitochondrial cytopathy. It discusses two mtDNA disorders, myoclonus epilepsy with ragged red fibers (MERRF) and mitochondrial myopathy encephalopathy, lactic acidosis, and stroke-like episodes (MELAS). Epilepsy occurs primarily in the

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 non-consanguineous parents following a normal pregnancy and uneventful spontaneous vaginal delivery. Investigations for infectious etiologies including blood and urine cultures as
