Lafora Disease

Lafora Disease (LD) has recently been widely accepted as being a GLycogen Storage Disease, it is an ultra-rare, progressive, autosomal recessive neurodegenerative disorder characterized by intractable seizures, difficulty walking, muscle spasms, neurological deterioration, rapid cognitive decline, dementia, and death typically within 10 years of onset. It is caused by loss-of-function mutations in either the laforin gene (EPM2A) or malin gene (EPM2B) and is associated with gradual accumulation of Lafora bodies, aggregates of poorly branched, hyperphosphorylated, insoluble glycogen also known as polyglusan.
According to the United States National Institutes of Health (NIH), the signs and symptoms of Lafora disease generally appear during late childhood or adolescence. Prior to the onset of symptoms, affected children appear to have normal development although some may have isolated convulsions in infancy or early childhood.

The most common feature of Lafora disease is recurrent seizures. These seizures are considered "progressive" because they generally become worse and more difficult to treat over time.

With the onset of seizures, people with Lafora disease often begin showing signs of cognitive decline. This may include behavioral changes, depression, confusion, ataxia (difficulty controlling muscles), dysarthria, and eventually, dementia. By the mid-twenties, most affected people lose the ability to perform the activities of daily living; have continuous myoclonus; and require tube feeding and comprehensive care.


Valerion Therapeutics, a Massachusetts based biotechnology company is developing, VAL-0417, a novel fusion protein that combines Valerion’s delivery antibody (3E10) linked to amylase to uniquely target neuronal glycogen through enhanced delivery to affected tissues. In preclinical proof-of-concept studies, Valerion and collaborators at the University of Kentucky demonstrated in vitro and in vivo, the ability to deliver VAL-0417 to the skeletal muscle and brain with retention of up to 24 hours following intracerebroventricular (ICV) injection in Lafora mouse models. These data were presented in a presentation titled “Lafora Body Degradation by a Therapeutic Enzyme for the Treatment of Lafora Disease,” at the 2017 Lafora Disease Workshop, a satellite symposium of the 32nd International Epilepsy Congress held September 2-6, 2017 in Barcelona, Spain.
