PEBEL; Early-onset progressive encephalopathy with brain edema and/or leukoencephalopathy
Description
Early-onset progressive encephalopathy with brain edema and/or leukoencephalopathy (PEBEL) is an autosomal recessive infancy-onset disease characterized by ataxia, cerebellar edema, spinal myelopathy, and skin lesions. It is triggered 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 PEBEL1. Biallelic pathogenic variants in the NAD(P)HX dehydratase (NAXD) cause PEBEL2.
