A group of severe neurodegenerative diseases characterized by intracellular accumulation of autofluorescent wax-like lipid materials (CEROID; LIPOFUSCIN) in neurons. There are several subtypes based on mutations of the various genes, time of disease onset, and severity of the neurological defects such as progressive DEMENTIA; SEIZURES; and visual failure.
Note: Use of the qualifier "multiple interactions" designates that the annotated interaction
is comprised of a complex set of reactions and/or regulatory events, possibly involving
additional chemicals and/or gene products.
