Description : The neuronal ceroid lipofuscinoses (NCL; CLN) are a clinically and genetically heterogeneous
group of neurodegenerative disorders characterized by the intracellular accumulation
of autofluorescent lipopigment storage material in different patterns ultrastructurally.
The clinical course includes progressive dementia, seizures, and progressive visual
failure (Mole et al., 2005). For a general phenotypic description and a discussion
of genetic heterogeneity of CLN, see CLN1 (256730). The hallmark of CLN3 is the ultrastructural
pattern of lipopigment with a 'fingerprint' profile, which can have 3 different appearances:
pure within a lysosomal residual body; in conjunction with curvilinear or rectilinear
profiles; and as a small component within large membrane-bound lysosomal vacuoles.
The combination of fingerprint profiles within lysosomal vacuoles is a regular feature
of blood lymphocytes from patients with CLN3 (Mole et al., 2005).;
Inheritance : Autosomal recessive;
Molecular basis : Caused by mutation in the CLN3 lysosomal/endosomal transmembrane protein, Battenin
gene (CLN3, 607042.0001);
Laboratory abnormalities : Lipopigment in extraneuronal cells; 'Fingerprint profiles' ultrastructurally in cells; 'Curvilinear profiles' ultrastructurally in cells;
