[Lafora disease with a fatal outcome].

Area of Science:

• Neurology
• Genetics
• Pathology

Background:

• Lafora disease is a rare, fatal, inherited neurodegenerative disorder characterized by progressive myoclonic epilepsy.
• Key pathological hallmarks include the accumulation of polyglucosane (Lafora) bodies in neuronal and non-neuronal tissues.

Observation:

• This report details a fatal case of Lafora disease in an 18-year-old patient.
• Clinical presentation included severe neurological deterioration culminating in death.
• Autopsy findings revealed macroscopic and microscopic evidence of Lafora bodies in the brain, myocardium, liver, and sweat gland ducts.

Findings:

• Genetic analysis confirmed Lafora disease through a homozygous mutation in the EPM2A gene (laforin).
• The post-mortem examination provided detailed macroscopic and histopathological data of Lafora body deposition across multiple organs.
• This case is unique for its comprehensive documentation of autopsy findings in a fatal Lafora disease presentation.

Implications:

• This detailed case study expands the understanding of Lafora disease's systemic pathology and fatal progression.
• The findings underscore the importance of integrating genetic, clinical, and autopsy data for accurate diagnosis and research.
• Further research into Lafora body formation and EPM2A gene function is warranted to develop targeted therapies.
