The SLC30A10 gene provides instructions for making a protein that transports the element manganese across cell membranes. Manganese is important for many cellular functions, but large amounts are toxic, particularly to brain and liver cells. Excess amounts of the element are normally removed from the body through bile, which is a fluid produced in the liver that is important for digestion and the removal of waste materials.
The SLC30A10 protein is found in the membranes surrounding liver cells and nerve cells in the brain, as well as in the membranes of structures within these cells. It protects cells from high concentrations of manganese by removing manganese when levels become elevated. In the liver, the SLC30A10 protein transports manganese out of cells into bile so that the element can be removed from the body.

Hypermanganesemia with dystonia
More than a dozen mutations in the SLC30A10 gene have been identified in people with hypermanganesemia with dystonia, polycythemia, and cirrhosis (HMDPC, also known as hypermanganesemia with dystonia 1). This inherited disorder is characterized by high levels of manganese (hypermanganesemia) in the blood, brain, and liver. The disorder causes movement problems, such as involuntary tensing of the muscles (dystonia); an increased number of red blood cells (polycythemia); and liver abnormalities, including irreversible liver disease (cirrhosis).
Mutations in the SLC30A10 gene impair the transport of manganese out of the cell, allowing the element to build up in brain and liver cells. Manganese accumulates in a region of the brain that helps control movement, damaging nerve cells and leading to the movement problems characteristic of HMDPC. Damage caused by a buildup of manganese in the liver causes the characteristic liver problems. High levels of manganese help increase the production of red blood cells, so excess amounts of this element may underlie polycythemia.More About This Health Condition
