Confirmation of ACER3-related recessive neurodegeneration, and preliminary evidence for feasibility of biochemistry-based ACER3 variant classification

These findings were presented at the ASHG 2018.


  • Ceramidases cleave ceramides into fatty acids and sphingosine
  • They are thereby important players in lipid metabolism
  • Knockout of the murine alkaline ceramidase 3 (Acer3) entails a late onset gait phenotype, Purkinje cell degeneration and dysregulation of several ceramides
  • A homozygous missense variant in the human homologue ACER3 has been associated with leukodystrophy and abnormal ceramide/sphingolipid profiles in two patients from a single family
