Progressive Myoclonic Epilepsy Type 5

EPM5


Presentation

  • The gene, denoted EPM2, presents alternative splicing in the 5' and 3' end regions. Mutational analysis revealed that EPM2 patients are homozygous for loss-of-function mutations in EPM2.[moh-it.pure.elsevier.com]
  • In this paper we present a case, who presented with treatment-resistant seizures and progressive mental failure and was finally diagnosed as Lafora Body disease. 2.[pubs.sciepub.com]
  • The authors show that the function of the channel is actually reduced by 80% when the mutant channel is present in a 1:1 ratio with wildtype KCNC1. This is what you need to know.[epilepsygenetics.net]

Movement Disorder
  • Together with Professor Stanley Fahn, of the Neurological Institute in New York, he founded the Movement Disorder Society and its scientific journal Movement Disorders. He died in 1998.[books.google.com]
  • Hyperkinetic movement disorders comprise a range of diseases characterized by unwanted and uncontrollable, or poorly controllable, involuntary movements.[books.google.de]
  • Therefore, FAME may actually be better characterized as a movement disorder with concomitant seizures rather than a familial epilepsy syndrome.[euroepinomics.wordpress.com]
Onset in Adolescence
  • Other features suggestive of the diagnosis include normal intelligence, onset around adolescence, and a family history of the condition.[emedicine.medscape.com]

Treatment

  • Given the rarity of these diseases, the treatments outlined in the abstracts are not always evidence based. The information in the abstracts isnot intended to replace existing local, regional or country specific recommendations and guidelines.[orpha.net]
  • Therefore new treatment modalities are needed. Experimental treatments of ULD patients with dopamine agonists have relieved myoclonic symptoms.[clinicaltrials.gov]
  • Imaging studies such as diffusion tensor imaging (DTI) may have a role in monitoring response to treatment. Aim: Monitoring response to treatment of CTX. Question: To evaluate monitoring response to CDCA therapy.[2015.dgn2013.de]

Prognosis

  • A clinical study comprising 124 cases with special reference to clinical presentation and prognosis.[hastane.hacettepe.edu.tr]
  • Patients usually require lifelong anticonvulsant therapy, but their overall prognosis is generally good.[emedicine.medscape.com]
  • LD has an unfavorable prognosis, and patients usually die within 10 years of the clinical findings at onset. 4.[pubs.sciepub.com]
  • .  The prognosis is very poor; death occurring at an average of 4–6 years after the onset. 49.[slideshare.net]

Etiology

  • They are organised into groups, and further divided into clinical, etiological or histopathological sub-types.[orpha.net]
  • Over the last two decades, considerable developments have occurred in the field of PMEs and they have been recognized as a group of syndromes with specific etiologies. 2 Macular cherry red spot is an important diagnostic marker in children with myoclonic[neurologyindia.com]
  • Mefford Abstract Epilepsy-aphasia syndromes (EAS) are a group of rare, severe epileptic encephalopathies of unknown etiology with a characteristic electroencephalogram (EEG) pattern and developmental regression particularly affecting language.[citeulike.org]
  • (See Etiology.) Known mutations include ion channel proteins, such as the beta-4 subunit of calcium channels and the chloride channel 2 protein.[emedicine.medscape.com]
  • Similarities among the deposits of type IV glycogenosis and Lafora bodies suggest a common structure and, possibly, common etiological factors ( 16 ).[academic.oup.com]

Pathophysiology

  • His main research interest is in movement disorders, specifically the merging of clinical, electrophysiological and imaging methods to provide insights into the pathophysiology of conditions like dystonia and Parkinson's disease.[books.google.com]
  • But recognizing the phenomenology and understanding the pathophysiology are essential to ensure appropriate treatment. Hyperkinetic Movement Disorders provides a clinical pathway for effective diagnosis and management of these disorders.[books.google.de]
  • For more information, see the following: Pathophysiology JME is an idiopathic primary generalized epilepsy syndrome.[emedicine.medscape.com]

Prevention

  • Mutations in the EPM2A gene prevent cells from making functional laforin, while NHLRC1 gene mutations prevent the production of functional malin. It is unclear how a loss of either of these proteins leads to the formation of Lafora bodies.[ghr.nlm.nih.gov]
