background:
CLN6, a 311 amino acid protein, has seven predicted transmembrane domains and is conserved across vertebrates. The CLN6 protein localizes to the endoplasmic reticulum but contributes to lysosomal function. Mutations in the CLN6 gene cause variant late-onset infantile neuronal ceroid lipofuscinosis (vLINCL), a lysosomal storage disorder marked by progressive mental deterioration and blindness; part of a group of severe inherited neurodegenerative disorders affecting children wherein lysosomes accumulate storage material, causing the death of neurons. CLN6 is one of eight proteins, including CLN1-8, that are associated with NCL.
Function:
Defects in CLN6 are the cause of variant late onset infantile neuronal ceroid lipofuscinosis (vLINCL).
Subunit:
Endoplasmic reticulum membrane; Multi pass membrane protein.
Subcellular Location:
Endoplasmic reticulum membrane; Multi-pass membrane protein.
DISEASE:
Defects in CLN6 are the cause of neuronal ceroid lipofuscinosis type 6 (CLN6) [MIM:60356]. A form of neuronal ceroid lipofuscinosis. Neuronal ceroid lipofuscinoses are progressive neurodegenerative, lysosomal storage diseases characterized by intracellular accumulation of autofluorescent liposomal material, and clinically by seizures, dementia, visual loss, and/or cerebral atrophy. The lipopigment patterns observed most often in neuronal ceroid lipofuscinosis type 6 comprise mixed combinations of granular, curvilinear, and fingerprint profiles.
Defects in CLN6 are the cause of neuronal ceroid lipofuscinosis type 4A (CLN4A) [MIM:204300]. An adult-onset neuronal ceroid lipofuscinosis. Neuronal ceroid lipofuscinoses are progressive neurodegenerative, lysosomal storage diseases characterized by intracellular accumulation of autofluorescent liposomal material, and clinically by seizures, dementia, visual loss, and/or cerebral atrophy. CLN4A has no visual involvement and is characterized by progressive myoclonic epilepsy.
