A severe form of neuronal ceroid lipofuscinosis with onset at birth and characteristics of primary microcephaly, neonatal epilepsy and death in early infancy. It is a rare form of neuronal ceroid lipofuscinosis with only around 10 cases reported in the literature so far. Patients present with postnatal respiratory insufficiency, seizures immediately after birth and a lower than normal head circumference. Transmitted in an autosomal recessive manner and is caused by mutations in the CTSD gene (designated CLN10; 11p15.5) encoding the lysosomal enzyme cathepsin D.
