Enzyme based diagnosis of type 1 and 2 neuronal ceroid lipofuscinoses

The neuronal ceroid-lipofuscinoses.

The neuronal ceroid-lipofuscinoses (NCLs) collectively constitute the most common group of neurodegenerative diseases in childhood and usually show an autosomal recessive mode of inheritance. Despite varying ages of onset and clinical course characterized in most instances by progressive mental and motor deterioration, blindness, epileptic seizures, and premature death, all forms of NCL show un...

Towards understanding the neuronal ceroid lipofuscinoses.

The neuronal ceroid lipofuscinoses (NCLs) are a group of genetic progressive brain diseases of children and young adults, characterized by a decline of mental and other capacities, epilepsy, and visual loss through retinal degeneration. The common pathology of NCLs is that of a storage disorder with accumulation of an autofluorescent material, ceroid lipofuscin, in combination with the degenera...

Significance of muscle biopsies in neuronal ceroid-lipofuscinoses.

Muscle specimens obtained at necropsy from four cases of neuronal ceroid-lipofuscinosis (NCL), three of the juvenile and one of the late infantile type, and a muscle biopsy from a fifth patient with the juvenile type of NCL, all showed curvilinear bodies typical of NCL within the muscle fibres. The pigments were autofluorescent. It appears that skeletal muscle is a reliable tissue source for th...

The neuronal ceroid lipofuscinoses: the same, but different?

The NCLs (neuronal ceroid lipofuscinoses) (also known as Batten disease) are a group of at least ten fatal inherited storage disorders. Despite the identification of many of the disease-causing genes, very little is known about the underlying disease mechanisms. However, now that we have mouse or large-animal models for most forms of NCL, we can investigate pathogenesis and compare what happens...
