Overview
Alpers' disease, also called Alpers' syndrome,[1] progressive neuronal degeneration of childhood,[1] progressive sclerosing poliodystrophy, and progressive infantile poliodystrophy, is a progressive degenerative disease of the central nervous system that occurs in infants and children. It is an autosomal recessive disorder that is sometimes seen in siblings.
Classification
- There is no established system for the classification of Alpers disease.
Pathophysiology
- Alpers disease is inherited in an autosomal recessive pattern.
- Mutation in POLG1 gene reduces polymerase gamma functionality, resulting in defective mitochondrial DNA.[2]
- Brain, liver and skeletal muscles are most involved due to high number of mitochondria.[3]
Causes
- Alpers disease is a mitochondrial disorder caused by a mutation in the POLG1 gene.[4]
Differentiating Alpers disease from other Diseases
- Alpers disease must be differentiated from other mitochondrial diseases caused POLG gene mutation:
- Childhood Myocerbrohepatopathy Spectrum Disorder[5]
- Myoclonus epilepsy myopathy sensory ataxia (MEMSA)
- Progressive external ophthalmoplegia[6]
Epidemiology and Demographics
- The prevalence of Alpers disease is approximately 1 per 100,000 individuals worldwide.
- Alpers disease affects men and women equally.
- Higher carrier frequency is seen in the Northern European population.[3]
Risk Factors
- There are no established risk factors for Alpers disease.
Screening
- There is insufficient evidence to recommend routine screening for Alpers disease.
Natural History, Complications, and Prognosis
- Prognosis is generally poor,
Prognosis
The prognosis for individuals with Alpers' disease is poor. Those with the disease usually die within their first decade of life. Liver failure is usually the cause of death, although cardiorespiratory failure may also occur.
Eponym
It is named for Bernard Jacob Alpers.[7][8][9]
