Summaries for Encephalopathy, Acute, Infection-Induced 4

About this section
OMIM : 56 Acute encephalopathy is a severe neurologic complication of an infection that usually occurs in children. It is characterized by a high-grade fever accompanied within 12 to 48 hours by febrile convulsions, often leading to coma, multiple-organ failure, brain edema, and high morbidity and mortality. The infections are usually viral, particularly influenza, although other viruses and even mycoplasma have been found to cause the disorder (summary by Chen et al., 2005; Shinohara et al., 2011). For a discussion of genetic heterogeneity of susceptibility to acute infection-induced encephalopathy, see 610551. (614212)

MalaCards based summary : Encephalopathy, Acute, Infection-Induced 4, also known as encephalopathy, acute, infection-induced, 4, susceptibility to, is related to encephalopathy and viral encephalitis. An important gene associated with Encephalopathy, Acute, Infection-Induced 4 is CPT2 (Carnitine Palmitoyltransferase 2). The drugs Dexamethasone acetate and Dexamethasone have been mentioned in the context of this disorder. Affiliated tissues include brain and heart, and related phenotypes are seizures and fever

UniProtKB/Swiss-Prot : 73 Encephalopathy, acute, infection-induced, 4: A severe neurologic complication of an infection. It manifests within days in otherwise healthy children after common viral infections, without evidence of viral infection of the brain or inflammatory cell infiltration. In affected children, high-grade fever is accompanied within 12 to 48 hours by febrile convulsions, often leading to coma, multiple-organ failure, brain edema, and high morbidity and mortality. The infections are usually viral, particularly influenza, although other viruses and even mycoplasma have been found to cause the disorder.
