| 610551 | OMIM | Encephalopathy, acute, infection-induced, Herpes-specific, 1 (IIAE1) | A rare complication of human herpesvirus 1 (HHV-1) infection, occurring in only a small minority of HHV-1 infected individuals. It is characterized by hemorrhagic necrosis of parts of the temporal and frontal lobes. Onset is over several days and involves fever, headache, seizures, stupor, and often coma, frequently with a fatal outcome. Disease susceptibility is associated with variants affecting the gene represented in this entry. Mutations in UNC93B1 resulting in autosomal recessive UNC93B1 deficiency predispose otherwise healthy individuals to isolated herpes simplex encephalitis due to impaired IFNs production. UNC93B1 deficiency, however, does not compromise immunity to most pathogens, unlike most known primary immunodeficiencies. |
