NCIt definition : Human PPT1 wild-type allele is located in the vicinity of 1p34.2 and is approximately
26 kb in length. This allele, which encodes palmitoyl-protein thioesterase 1 protein,
plays a role in the removal of fatty acyl chains from proteins or peptides during
lysosomal degradation. Mutation in the gene is associated with neuronal ceroid-lipofuscinosis
