Cathepsin D deficiency underlies congenital neuronal ceroid-lipofuscinosis (NCL). It represents the earliest-onset and the most aggressive form of the NCL, leading to extreme brain atrophy and death soon after birth. Cathepsin D is a lysosomal protein encoded by the CTSD gene. Recently, novel mutations in CTSD with a juvenile onset of NCL have been reported.
