Possible Causes

Congenital Neuronal Ceroid Lipofuscinosis

Cathepsin D (Ctsd) is a ubiquitously expressed aspartic protease functioning primarily in the acidic endosomal/lysosomal cell compartment. At an age of 26 1 days, mice with constitutive Ctsd deficiency (Ctsd(-/-)) die from a neurodegenerative lysosomal storage disease equivalent to the congenital neuronal ceroid[…] [ncbi.nlm.nih.gov]
