Summaries for Encephalitis/encephalopathy, Mild, with Reversible Myelin...

About this section
OMIM : 57 MMERV is an episodic acute reversible encephalopathy that occurs in children and is frequently associated with a trigger, such as a febrile illness. Affected individuals have impaired consciousness, delirious behavior, and/or seizures with lip smacking or eye deviation. These changes are associated with white matter lesions in the brain that often occur in the splenium of the corpus callosum, but may occur in surrounding areas. The acute phase of the disorder can be treated with steroids, and most patients make a full neurologic recovery between episodes with no sequelae (summary by Kurahashi et al., 2018). (618113)

MalaCards based summary : Encephalitis/encephalopathy, Mild, with Reversible Myelin Vacuolization, also known as mmerv, is related to severe acute respiratory syndrome and encephalitis. An important gene associated with Encephalitis/encephalopathy, Mild, with Reversible Myelin Vacuolization is MYRF (Myelin Regulatory Factor). The drugs Dexmedetomidine and Analgesics have been mentioned in the context of this disorder. Affiliated tissues include brain and eye, and related phenotypes are seizures and delayed speech and language development

UniProtKB/Swiss-Prot : 74 Encephalitis/encephalopathy, mild, with reversible myelin vacuolization: An autosomal dominant disease characterized by episodes of acute encephalitis associated with impaired consciousness, delirious behavior, seizures, and reversible splenial lesions observed on diffusion magnetic resonance imaging. Most patients completely recover and there are no neurologic sequelae. MMERV occurs in children and is frequently associated with a trigger, such as a febrile illness.
