Summaries for Epilepsy, Pyridoxine-Dependent

About this section
NIH Rare Diseases:48 Pyridoxine-dependent epilepsy is a condition that involves seizures beginning in infancy or, in some cases, before birth. those affected typically experience prolonged seizures lasting several minutes (status epilepticus). these seizures involve muscle rigidity, convulsions, and loss of consciousness (tonic-clonic seizures). anticonvulsant drugs, which are usually given to control seizures, are ineffective in people with pyridoxine-dependent epilepsy. instead, people with this type of seizure are medically treated with large daily doses of pyridoxine (a type of vitamin b6 found in food). mutations in the aldh7a1 gene cause pyridoxine-dependent epilepsy. this gene is inherited in an autosomal recessive fashion. last updated: 7/23/2013

MalaCards based summary: Epilepsy, Pyridoxine-Dependent, also known as pyridoxine-dependent epilepsy, is related to epilepsy and microcephaly, and has symptoms including seizures, seizures and Array. An important gene associated with Epilepsy, Pyridoxine-Dependent is ALDH7A1 (Aldehyde Dehydrogenase 7 Family Member A1).

Genetics Home Reference:25 Pyridoxine-dependent epilepsy is a condition that involves seizures beginning in infancy or, in some cases, before birth. Those affected typically experience prolonged seizures lasting several minutes (status epilepticus). These seizures involve muscle rigidity, convulsions, and loss of consciousness (tonic-clonic seizures). Additional features of pyridoxine-dependent epilepsy include low body temperature (hypothermia), poor muscle tone (dystonia) soon after birth, and irritability before a seizure episode. In rare instances, children with this condition do not have seizures until they are 1 to 3 years old.
