A rare epilepsy syndrome characterised by late-onset (after 1 year old) epileptic spasms that occur in clusters, associated with tonic seizures, atypical absences and cognitive deterioration. Language difficulties and behaviour problems are frequently present. EEG is characterised by a temporal or temporofrontal slow wave or spike focus combined with synchronous spike-waves and no hypsarrhythmia or background activity.	componente obsoleto (metadato fundacional)

A rare epilepsy syndrome defined by seizures originating in limbic areas of the mesial temporal lobe, particularly in the hippocampus, amygdala, and in the parahippocampal gyrus and its connections, and hippocampal sclerosis, usually unilateral or asymmetric. It is frequently associated with an initial precipitating event, such as febrile seizures, hypoxia, intracranial infection or head trauma, most often occurring in the first five years of life, followed by a latent period without seizures. Typical seizures consist of a characteristic aura that is frequently a rising epigastric sensation associated with emotional disturbances, illusions, and autonomic symptoms (widened pupils, palpitations), progressive impairment of consciousness, oro-alimentary automatisms (lip smacking, chewing, licking, tooth grinding), behavioral arrest, head deviation, dystonic postures, hand and verbal automatisms. Seizures are followed by postictal dysfunction. Initially, seizures are easily controlled with antiepileptic drugs, later they frequently become refractory and associated with progressive behavioral changes and memory deficits.	componente obsoleto (metadato fundacional)

A rare form of pseudohyperaldosteronism with characteristics of very early-onset and severe hypertension associated with low renin levels and hypoaldosteronism. Caused by homozygous or compound heterozygous loss-of-function mutations or deletions in the HSD11B2 gene (16q22). In all cases, these mutations lead to abolition or a marked decrease in the activity of 11-beta-hydroxysteroid dehydrogenase type 2 (11-beta-HSD2), an enzyme involved in the conversion of cortisol to cortisone. Transmission is autosomal recessive.	componente obsoleto (metadato fundacional)
A rare form of spinal muscular atrophy with characteristics of the neonatal onset of severe hypotonia, areflexia, profound weakness, multiple congenital contractures, facial dysmorphic features (myopathic face with open, tent-shaped mouth), cryptorchidism, and mild skeletal abnormalities (kyphosis, scoliosis), that is often preceded by polyhydramnios and reduced fetal movements in utero and followed by bone fractures shortly after birth. Patients have a limited life span, often succumbing to the disease within 2 years, as muscle weakness is progressive and chest muscle involvement eventually leads to ventilatory insufficiency and respiratory failure.	componente obsoleto (metadato fundacional)
A rare form of superficial corneal dystrophy with recurrent episodes of epithelial erosions from childhood in the absence of associated diseases. The erosions begin spontaneously or are precipitated by minor trauma, dust or smoke. The condition may become apparent by 6 months of age, but as a rule it only starts at 4 to 6 years of age. Most patients have attacks of redness, photophobia, epiphora, and ocular pain. Some experience a burning sensation and report sensitive eyes for years. Vision is sometimes impaired.

A rare functional disorder with recurrent episodes of torticollis posturing of the head (inclination or tilting of the head to one side) in healthy children. The prevalence is unknown and the benign nature of the disorder probably means that it is under reported. Onset occurs within the first year of life with episodes occurring between every few weeks and every few months. The duration of the torticollis varies between patients, but usually lasts from a few hours to a few days. The frequency and duration of the torticollis episodes decrease as the patient gets older and episodes usually stop completely by 5 years of age. The disorder usually occurs sporadically, but familial occurrence has been reported.	componente obsoleto (metadato fundacional)

A rare gastroenterologic disease characterised by the histopathological finding of a thickened gastric subepithelial collagen layer in association with an inflammatory infiltrate in the lamina propria. Patients typically present with upper abdominal pain and severe iron deficiency anaemia. The condition is not commonly associated with autoimmune diseases, and involvement of the colon is less frequent than in the adult form. The disease takes a generally benign course with limited long-term morbidity and no increased mortality.	componente obsoleto (metadato fundacional)

A rare genetic X-linked syndromic intellectual disability disorder characterised by mild to severe intellectual disability, infancy-onset seizures, post-natal microcephaly, cerebral cortical malformations, dysmorphic facial features (including long, narrow face, almond-shaped palpebral fissures, epicanthic folds, high nasal bridge, malar flattening, posteriorly rotated ears, high arched palate, crowded teeth, micrognathia) and thin body habitus. Long and slim fingers/toes, strabismus, hypotonia, spasticity, optic disc atrophy, and behavioural problems (aggression, attention deficit hyperactivity disorder and irritability) are additional features.

A rare genetic X-linked syndromic intellectual disability disorder with characteristics of moderate to severe intellectual disability associated with epilepsy, short stature, autistic features and behavioral problems, such as self- injury and aggressive outbursts. Observed facial dysmorphism includes brachycephaly, prominent supraorbital ridges, and deep-set eyes. Additional variable manifestations include malposition of feet, asthenic habitus, hyporeflexia, bowel occlusions, hydronephrosis, horseshoe kidney, delayed motor development and disturbed sleep-wake cycle. Caused by mutation in the GRIA3 gene.	componente obsoleto (metadato fundacional)

A rare genetic adrenal disease with characteristics of diminished corticosteroid-binding capacity associated with normal or low plasma corticosteroid-binding globulin concentration and reduced total plasma cortisol levels. Patients typically present chronic pain, fatigue and hypo/hypertension. Can be caused by heterozygous or homozygous mutation in the SERPINA6 gene on chromosome 14q32.	componente obsoleto (metadato fundacional)

A rare genetic autosomal recessive axonal hereditary motor and sensory neuropathy disease with characteristics of prenatal onset of a severe sensorimotor axonal polyneuropathy reflected by reduced fetal movement and polyhydramnios. The disease manifests at birth with respiratory failure requiring mechanical ventilation, profound muscular hypotonia, rapidly progressing distal muscle weakness and absent deep tendon reflexes in the absence of contractures leading to death before 8 months of age. Neuropathological findings show severe loss of large and medium sized myelinated fibers without signs of demyelination.	componente obsoleto (metadato fundacional)
