An important gene associated with Ceroid Lipofuscinosis, Neuronal, 1 is PPT1 (Palmitoyl-Protein Thioesterase 1), and among its related pathways/superpathways are Ciliary landscape and Fatty acyl-CoA biosynthesis. The drugs Cysteamine and Acetylcysteine have been mentioned in the context of this disorder. Affiliated tissues include brain and eye, and related phenotypes are vascular granular osmiophilic material deposition and psychomotor deterioration
