Pyridoxine-Dependent Epilepsy: An Expanding Clinical Spectrum.
BACKGROUND Pyridoxine-dependent epilepsy is a rare autosomal recessive epileptic encephalopathy caused by antiquitin (ALDH7A1) deficiency. In spite of adequate seizure control, 75% of patients suffer intellectual developmental disability. Antiquitin deficiency affects lysine catabolism resulting in accumulation of α-aminoadipic semialdehyde/pyrroline 6' carboxylate and pipecolic acid. Beside ne...
متن کاملPyridoxine dependent seizures--a wider clinical spectrum.
We report 4 infants with pyridoxine dependent seizures who had clinical features that led to diagnostic uncertainty. Their clinical course was unusual in 1 or more of the following: later onset of initial seizures; a seizure free period after taking of anticonvulsants, but before taking of pyridoxine; a long remission after withdrawal of pyridoxine; and atypical seizure type. This report illust...
متن کاملGenotypic and phenotypic spectrum of pyridoxine-dependent epilepsy (ALDH7A1 deficiency)
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...
متن کاملPyridoxine-Dependent Epilepsy
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 ...
متن کاملPyridoxine dependent epilepsy: a suggestive electroclinical pattern.
AIMS To determine if there is an electroencephalographic pattern suggestive of pyridoxine dependent epilepsy that could be used to improve the chances of early diagnosis. METHODS A retrospective study was made of all the clinical records and electroencephalograms of neonates identified with pyridoxine dependent seizures between 1983 and 1994, at this hospital. Neonates whose seizures began af...
