Epilepsy

The chain reaches the human disease alopecia-epilepsy-pyorrhea-intellectual disability syndrome, which Mondo defines as: “Alopecia-epilepsy-pyorrhea-intellectual disability syndrome is characterized by congenital permanent alopecia universalis, intellectual disability, psychomotor epilepsy and periodontitis (pyorrhea). Total permanent alopecia and pyorrhea are invariably concomitant while intellectual disability and psychomotor epilepsy are observed in most patients. No other abnormality of nails or skin (apart from absence of hair) has been reported. Transmission is autosomal dominant.” It reaches 31 more human diseases, listed below.

Mondo disease Name Found by
MONDO:0007085 alopecia-epilepsy-pyorrhea-intellectual disability syndrome Alopecia-epilepsy-pyorrhea-intellectual disability syndrome is characterized by congenital permanent alopecia universalis, intellectual disability, psychomotor epilepsy and periodontitis (pyorrhea). Total permanent alopecia and pyorrhea are invariably concomitant while intellectual disability and psychomotor epilepsy are observed in most patients. No other abnormality of nails or skin (apart from absence of hair) has been reported. Transmission is autosomal dominant. OMIA's OMIM numbers

MONDO:0007435 dentatorubral-pallidoluysian atrophy A progressive neurodegenerative disease caused by expanded CAG repeats in the ATN1 gene. It is characterized by involuntary movements, ataxia, epilepsy, mental disorders, cerebellar atrophy, and cognitive decline. Neuropathological changes consist of combined degeneration of the dentatorubral and pallidoluysian systems. Affected individuals mostly have heterozygous expanded CAG repeat units (usually with lengths of 48 tandem repeat units or more) in exon 5 of the ATN1 gene. Clinical presentation and onset depend on the size of the repeat due to the toxicity threshold of the expanded polyglutamine (polyQ) tract in the ATN1 gene product. OMIA's OMIM numbers

MONDO:0700090 epilepsy, familial temporal lobe, 1 An autosomal dominant condition caused by mutation(s) in the LGI1 gene, encoding leucine-rich glioma-inactivated protein 1. It is characterized by partial seizures originating in the temporal lobe and often accompanied by auditory sensory manifestations. OMIA's OMIM numbers
MONDO:0017325 epilepsy, focal, with speech disorder and with or without impaired intellectual development A rare intellectual disability and epilepsy syndrome due to mutation in GRIN2A gene. It is characterized by global developmental delay and mild to profound intellectual disability, multiple types of usually intractable focal and generalized seizures with variable abnormal EEG findings, and bilateral progressive parenchymal volume loss and thin corpus callosum on brain MRI. OMIA's OMIM numbers
MONDO:0009186 epilepsy, photogenic, with spastic diplegia and impaired intellectual development OMIA's OMIM numbers
MONDO:0009188 epilepsy-telangiectasia syndrome Epilepsy telangiectasia syndrome is characterized by intellectual deficit, epilepsy, palpebral conjunctival telangiectasias and diminished serum IgA, particular facies and a shortened fifth finger. It has been reported in six siblings from a Mexican family. It is probably transmitted as an autosomal recessive trait. OMIA's OMIM numbers
MONDO:0005579 idiopathic generalized epilepsy A generalised epilepsy that encompasses several common seizure phenotypes including childhood absence epilepsy, juvenile absence epilepsy, juvenile myoclonic epilepsy and epilepsy with generalized tonic-clonic seizures alone. These epilepsy syndromes have polygenic inheritance with or without environmental factors contributing to seizure susceptibility. Seizure types include one or a combination of absence seizures, myoclonic seizures and/or generalized tonic-clonic seizures. OMIA's OMIM numbers
MONDO:0009696 juvenile myoclonic epilepsy The most common hereditary idiopathic generalized epilepsy syndrome and is characterized by myoclonic jerks of the upper limbs on awakening, generalized tonic-clonic seizures manifesting during adolescence and triggered by sleep deprivation, alcohol intake, and cognitive activities, and typical absence seizures (30% of cases). OMIA's OMIM numbers
MONDO:0010790 MERRF syndrome A rare mitochondrial oxidative phosphorylation disorder characterized by myoclonic seizures, ataxia, generalized epilepsy, muscle weakness and ragged red fibers in the muscle biopsy. OMIA's OMIM numbers
MONDO:0008755 Moynahan syndrome A Mendelian disease characterized by congenital alopecia, early-onset epilepsy, intellectual disability and speech delay. Large stature, delayed bone development and abnormal electroencephalogram have also been associated. OMIA's OMIM numbers
MONDO:0008041 myoclonic epilepsy, Hartung type OMIA's OMIM numbers
MONDO:0958199 myoclonic epilepsy of Lafora 1 Any Lafora disease in which the cause of the disease is a variation in the EPM2A gene. OMIA's OMIM numbers
MONDO:0010830 neuronal ceroid lipofuscinosis 8 Any neuronal ceroid lipofuscinosis in which the cause of the disease is a mutation in the CLN8 gene. OMIA's OMIM numbers
MONDO:0007559 photoparoxysmal response 1 OMIA's OMIM numbers
MONDO:0009954 Ramon syndrome OMIA's OMIM numbers
MONDO:0007560 reading seizures A rare reflex epilepsy characterized by reading-induced seizures which in most cases present with orofacial/jaw myoclonus possibly extending to the upper limbs but can also manifest as dyslexia or alexia and visual symptoms. In both variants secondary generalized tonic-clonic seizures may evolve if the stimulus is not interrupted. The disease typically begins in the second or third decade of life and may be inherited in an autosomal dominant pattern. It usually takes a benign course with little tendency to spontaneous seizures. OMIA's OMIM numbers

MONDO:0007558 self-limited childhood occipital epilepsy A rare, genetic neurological disorder characterized by visual seizures and occipital epileptiform paroxysms reactive to ocular opening which present in infancy to mid-adolescence. Vomiting, tonic eye deviation and impairment of consciousness are typically associated with the Panayiotopoulos type, while visual hallucinations, ictal blindness and post-ictal headache are commonly observed in the Gastaut type. Electroencephalographic findings in both types are similar and include bilateral, synchronous, high voltage spike-wave complexes in a normal background activity located predominantly in the occipital lobes. OMIA's OMIM numbers
MONDO:0007295 self-limited epilepsy with centrotemporal spikes A childhood-onset epilepsy syndrome that is characterized by onset of seizures between 3 and 14 years (peak 8-9 years) that usually resolve by age 13 years, but can occasionally occur up to age 18 years of age. Both sexes are affected. Antecedent, birth and neonatal history is normal. A history of febrile seizure (in 5-15%) may be seen. A history of Panayiotopoulos syndrome may be present in a very small number of cases. Neurological exam and head size is normal. Development and cognition prior to onset of seizures is normal. During the course of the active epilepsy, behavioral and neuropsychological deficits may be found, particularly in language and executive functioning. These deficits improve when seizures remit.
