Summaries for Encephalopathy, Progressive, Early-Onset, with Brain Edema and/or...

OMIM : 56 Early-onset progressive encephalopathy with brain edema and/or leukoencephalopathy-1 (PEBEL1) is an autosomal recessive severe neurometabolic disorder characterized by rapidly progressive neurologic deterioration that is usually associated with a febrile illness. Affected infants tend to show normal early development followed by acute psychomotor regression with ataxia, hypotonia, respiratory insufficiency, and seizures, resulting in coma and death in the first years of life. Brain imaging shows multiple abnormalities, including brain edema and signal abnormalities in the cortical and subcortical regions (summary by Kremer et al., 2016). (617186)

MalaCards based summary : Encephalopathy, Progressive, Early-Onset, with Brain Edema and/or Leukoencephalopathy, 1, also known as encephalopathy, progressive, early-onset, with brain edema and/or leukoencephalopathy, is related to encephalopathy, progressive, early-onset, with brain edema and/or leukoencephalopathy, 2. An important gene associated with Encephalopathy, Progressive, Early-Onset, with Brain Edema and/or Leukoencephalopathy, 1 is NAXE (NAD(P)HX Epimerase). Affiliated tissues include brain and skin, and related phenotypes are brain atrophy and seizures

KEGG : 36 Early-onset progressive encephalopathy with brain edema and leukoencephalopathy (PEBEL) is an autosomal recessive infancy-onset disease characterized by ataxia, cerebellar edema, spinal myelopathy, and skin lesions. It is induced by febrile infections, leading to coma and finally to death within the first 3 years of life. NAXE mutations disrupt the cellular NAD(P)HX repair system and cause PEBEL.

UniProtKB/Swiss-Prot : 73 Encephalopathy, progressive, early-onset, with brain edema and/or leukoencephalopathy: An autosomal recessive severe neurometabolic disorder characterized by severe leukoencephalopathy usually associated with a trivial febrile illness. Affected infants tend to show normal early development followed by acute psychomotor regression with ataxia, hypotonia, respiratory insufficiency, and seizures. Disease course is rapidly progressive, leading to coma, global brain atrophy, and death in the first years of life. Brain imaging shows multiple abnormalities, including brain edema and signal abnormalities in the cortical and subcortical regions.
