According to the Online Mendelian Inheritance in Man database and relevant literature, PMEs can be divided into 12 subtypes: Unverricht-Lundborg disease (EPM1A), EPM1B, Lafora body
disease (EPM2A), Lafora body
disease (EPM2B), EPM3, action myoclonus with or without renal failure syndrome (EPM4), PME-ataxia syndrome (EPM5), North Sea PME (EPM6), EPM7, EPM8, EPM9, and EPM10.
In a presentation titled "Lafora Body
Degradation by a Therapeutic Enzyme for the Treatment of Lafora Disease," Valerion researchers and collaborators from 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.
The efficiency of diet has been reported in seizures related with Rett syndrome, Lafora body
disease, Landau Kleffner syndrome which is known as epileptic aphasia and neuronal seroid lipofuscinosis which is a lysosomal storage disease (26).
Lafora disease (also known as Lafora Body disease) is a rare neurometabolic disorder of autosomal recessive inheritance, which is generally caused by a mutation in EPM2A (4,8,13) or EPM2B genes.
