Svensk definition
En sällsynt, degenerativ nervsjukdom i tidig barndom kännetecknad av vakuolisering och demyelinisering av den vita substansen, vilket ger den ett svampigt utseende. Aspartoacylasbrist leder till ansam ling av N-acetylaspartat i astrocyterna. Tillståndet kan vara autosomalt recessivt ärftligt eller uppträda sporadiskt; det uppträder oftare hos individer av ashkenasisk judisk härkomst. I den form som drabbar nyfödda ses hypotoni och letargi, som snabbt leder till medvetslöshet och död.
Engelsk definition
A rare neurodegenerative condition of infancy or childhood characterized by white matter vacuolization and demeylination that gives rise to a spongy appearance. Aspartoacylase deficiency leads to an accumulation of N-acetylaspartate in astrocytes. Inheritance may be autosomal recessive or the illness may occur sporadically. This illness occurs more frequently in individuals of Ashkenazic Jewish descent. The neonatal form features the onset of hypotonia and lethargy at birth, rapidly progressing to coma and death. The infantile form features developmental delay, DYSKINESIAS, hypotonia, spasticity, blindness, and megalencephaly. The juvenile form is characterized by ATAXIA; OPTIC ATROPHY; and DEMENTIA.
