<div class="spaceAbove">Pyridoxine-dependent epilepsy ALDH7A1 (PDE-ALDH7A1) is characterized by seizures not well controlled with anti-seizure medication that are responsive clinically and electrographically to large daily supplements of pyridoxine (vitamin B6). This is true across a phenotypic spectrum that ranges from classic to atypical PDE-ALDH7A1. Intellectual disability is common, particularly in classic PDE-ALDH7A1. In classic PDE-ALDH7A1, untreated seizures begin within the first weeks to months of life. Dramatic presentations of prolonged seizures and recurrent episodes of status epilepticus are typical; recurrent self-limited events including partial seizures, generalized seizures, atonic seizures, myoclonic events, and infantile spasms also occur. Electrographic seizures can occur without clinical correlates. In atypical PDE-ALDH7A1, findings in untreated individuals can include late-onset seizures beginning between late infancy and age three years, seizures that initially respond to anti-seizure medication and then become intractable, seizures during early life that do not respond to pyridoxine but are subsequently controlled with pyridoxine several months later, and prolonged seizure-free intervals (=5 months) that occur after discontinuation of pyridoxine.</div>

<div class="spaceAbove">Thiamine metabolism dysfunction syndrome-5 (THMD5) is an autosomal recessive metabolic disorder due to an inborn error of thiamine metabolism. The phenotype is highly variable, but in general, affected individuals have onset in early childhood of acute encephalopathic episodes associated with increased serum and CSF lactate. These episodes result in progressive neurologic dysfunction manifest as gait disturbances, ataxia, dystonia, and spasticity, which in some cases may result in loss of ability to walk. Cognitive function is usually preserved, although mildly delayed development has been reported. These episodes are usually associated with infection and metabolic decompensation. Some patients may have recovery of some neurologic deficits (Mayr et al., 2011).&#13; For a discussion of genetic heterogeneity of disorders due to thiamine metabolism dysfunction, see THMD1 (249270).</div>

Epilepsy phenotypes include developmental and epileptic encephalopathy (DEE) associated with severe developmental delays and usually pharmacoresistant epilepsy with multiple seizure types; mild-to-moderate developmental and epileptic encephalopathy (mild/modDEE, or intermediate epilepsy) with partially treatable epilepsy; self-limited familial infantile epilepsy (SeLFIE, also known as benign familial infantile epilepsy or BFIE) with normal cognition and medically treatable seizures; neurodevelopmental delays with generalized epilepsy (NDDwGE); and neurodevelopmental disorder without epilepsy (NDDwoE) with mild-to-moderate intellectual disability (though it can be severe in ~10% of affected individuals). Hypotonia and movement disorders including dystonia, ataxia, and choreoathetosis are common in some phenotypes. Sudden unexpected death in epilepsy (SUDEP) has been reported in some affected individuals.</div>

<div class="spaceAbove">Asparagine synthetase deficiency (ASD) mainly presents as a triad of congenital microcephaly, severe developmental delay, and axial hypotonia followed by spastic quadriplegia. Low cerebrospinal fluid (CSF) asparagine level can help the clinician in differentiating this disorder from others. In most cases age of onset of apnea, excessive irritability, and seizures is soon after birth. Affected individuals typically do not acquire any developmental milestones. Spastic quadriplegia can lead to severe contractures of the limbs and neurogenic scoliosis. Feeding difficulties (gastroesophageal reflux disease, frequent vomiting, swallowing dysfunction, and gastroesophageal incoordination) are a significant problem in most affected individuals. A majority have cortical blindness. MRI findings are nonspecific but may include generalized atrophy and simplified gyral pattern.</div>

Most patients have onset of variable types of seizures between 4 and 13 months of age, but earlier onset in the first days of life has also been reported. Seizures are often triggered by fever, at least initially; status epilepticus may occur (summary by Nava et al., 2014 and Marini et al., 2018).&#13; For a general phenotypic description and a discussion of genetic heterogeneity of DEE, see 308350.</div>

<div class="spaceAbove">PLPBP deficiency is a treatable form of vitamin B6-dependent early-onset epileptic encephalopathy. Seizure onset is typically in the neonatal period (i.e., within the first 28 days after birth), and rarely in childhood after the neonatal period. Seizures are unresponsive to (or only partly responsive to) anti-seizure medications (ASMs) but typically show an immediate positive response to vitamin B6, given as either pyridoxine (PN) or pyridoxal 5'-phosphate (PLP). This therapy needs to be continued lifelong. In addition to vitamin B6 treatment, almost 60% of individuals require adjunct ASMs to achieve optimal seizure control. Although many individuals with PLPBP deficiency have normal motor, speech, and intellectual development, more than 50% have varying degrees of neurodevelopmental issues, including learning difficulties or intellectual disability (varying from mild to severe), delayed or absent speech development, or motor development abnormalities (most commonly mild hypotonia).</div>

<div class="spaceAbove">SCN3A-related neurodevelopmental disorder (SCN3A-ND) encompasses a spectrum of clinical severity associated with epilepsy and/or brain malformation. Affected individuals may have (a) developmental and epileptic encephalopathy (DEE) (i.e., intractable seizures with developmental delays associated with ongoing epileptiform EEG activity) with or without malformations of cortical development; or (b) malformations of cortical development with or without mild focal epilepsy. Some degree of early childhood developmental delay is seen in all affected individuals; the severity varies widely, ranging from isolated speech delay to severe developmental delay. Infantile hypotonia is common but may be mild or absent in those without DEE. In those with DEE, seizure onset is typically in the first six to 12 months of life. A variety of seizure types have been described. Seizures remain intractable to multiple anti-seizure medications in approximately 50% of individuals with DEE without malformations of cortical development (MCD) and in 90% of individuals with DEE and MCD. Seizures may be absent or infrequent in those without DEE. Brain MRI findings range from normal to showing thinning or hypoplasia of the corpus callosum, to various malformations of cortical development. Autonomic dysregulation, oromotor dysfunction leading to the need for gastrostomy tube placement, progressive microcephaly, hyperkinetic movement disorder, and cortical visual impairment can also be seen in those with DEE.</div>

Features may include difficulty walking, dizziness, slurred speech, headache, vomiting, and pain.

Prior to the EA, most patients have neonatal- or infantile-onset tonic or generalized tonic-clonic (GTC) seizures that may be severe and refractory to medication, but remit later in infancy or early childhood, either spontaneously or concurrently with medication. Some patients have mildly delayed development with speech delay and/or autistic features or mildly impaired intellectual development. However, others show normal psychomotor development. Treatment of the ataxic episodes with acetazolamide is effective in about 50% of patients (summary by Schwarz et al., 2019).&#13; For a phenotypic description and discussion of genetic heterogeneity of episodic ataxia, see EA1 (160120).</div>
