These links show how scientific research into mitochondrial dysfunction could benefit potentially millions of people affected by autism in the UK.
- The first evidence of mitochondrial dysfunction in ASD was reported 20 years ago (1998).
-
Since then, several medical studies have produced evidence to suggest that mitochondrial dysfunction is common in autism.
-
Up to 5% of children with autism also have mitochondrial disease.
-
10-20% of patients with mito also display features of autism.
-
It is still not known whether faulty mitochondria cause autism, or are part of the disease process.
-
Biochemical markers identical to those found in patients with mito disease are often found in the blood samples of autism patients. (This connection may be a useful tool in the diagnosis of ASD).
-
Genetic faults in mitochondrial DNA have been identified as a potential cause of ASD.
-
Whole exome sequencing has revealed that children with autism are 53% more likely to have heteroplasmic mutations (a mix of normal and faulty mitochondrial DNA) in certain regions of the mitochondrial genome.
-
Dietary supplements similar to those used to treat mitochondrial disease have been used to treat children with autism.
-
Research is underway to establish the precise relationship between mitochondrial dysfunction and autism, in order to assist development of new therapies.
