Written and reviewed by Dr Ibrahim Imam, Consultant Neurologist. Last reviewed .
Hypermanganesaemia with dystonia 1 (HMNDYT1): clinical features. This is caused by mutations in the SLC30A10 gene. Fully referenced neurology checklist.
Genetics
- This is caused by mutations in the SLC30A10 gene
- The gene product is a cell surface manganese efflux transporter
- The transmission is autosomal recessive
- The mutation leads to manganese accumulation in the liver and the brain
