Parkinson Disease and Complex Parkinsonism

Gene: SLC30A10

Green List (high evidence)

Biallelic mutations cause hypermanganesemia with dystonia-1 (HMNDYT1), increased serum manganese, motor neurodegeneration with extrapyramidal features, polycythemia, and hepatic dysfunction, Brain MRI shows hyperintensities in the basal ganglia). PMID: 22341971 (2 consang families with two consanguineous families with neurologic disorders including juvenile-onset dystonia, adult-onset parkinsonism, severe hypermanganesemia, polycythemia, and chronic hepatic disease, including steatosis and cirrhosis), 22341972 (8 families with HMNDYT1), 22926781 (one pt, and treatment: intravenous disodium calcium edetate (CaNa2-EDTA ethylenediaminetetraacetic acid), 1 g twice-daily (BD) over 5 days led to significantly increased 24-hour urinary manganese (12,852 nmol after 5 days) and reduced blood manganese levels. THIS IS ONE OF THE FEW DYSTONA-PARKINSONISM that is treatable), 22934317 (this is a gene review for this disorder). Keep this gene in both this gene to both the dystonia panel and pd.

Comment on list classification: Is a green gene on the early onset dystonia panel, version 1.0. The phenotype Hypermanganesemia with dystonia 1 includes Parkinsonism, though I am unsure whether this should be included on this panel.
