The SLC2A1 gene provides instructions for producing a protein called the glucose transporter protein type 1 (GLUT1). The GLUT1 protein is embedded in the outer membrane surrounding cells, where it transports a simple sugar called glucose into cells from the blood or from other cells for use as fuel.
Normal function
The SLC2A1 gene provides instructions for producing a protein called the glucose transporter protein type 1 (GLUT1). The GLUT1 protein is embedded in the outer membrane surrounding cells, where it transports a simple sugar called glucose into cells from the blood or from other cells for use as fuel.
In the brain, the GLUT1 protein is involved in moving glucose, which is the brain's main energy source, across the blood-brain barrier. The blood-brain barrier acts as a boundary between tiny blood vessels (capillaries) and the surrounding brain tissue; it protects the brain's delicate nerve tissue by preventing many other types of molecules from entering the brain. The GLUT1 protein also moves glucose between cells in the brain called glia, which protect and maintain nerve cells (neurons).

Wilson's disease
Wilson's disease is a genetic disorder in which copper builds up in the body, mainly in the liver and brain. Without any treatment, the build-up of copper can cause serious symptoms. Treatment is with medication to remove the excess copper and/or to prevent a further build-up of copper. How is Wilson's disease inherited. Wilson's disease is an.

Cystic fibrosis
Cystic fibrosis is a genetic disorder. Cystic fibrosis is an autosomal recessive disorder. This means that in order to develop cystic fibrosis you need to inherit two cystic fibrosis genes, one from your mother and one from your father. When two people who carry the cystic fibrosis gene have a child, there is a: 1 in 4 chance that the child will.

Haemochromatosis
Haemochromatosis is an inherited (genetic) disorder which causes the body to absorb too much iron from the diet. This excess iron causes damage to organs in which it builds up. The main treat... Because of the risk of developing a serious complication such as cirrhosis, treatment to remove iron buildup from the body is very important even if there.

Polycystic kidney disease
This means that one or more of your genes is faulty, which results in you making many cysts in the kidneys. There are different types of polycystic kidney disease: Autosomal dominant polycystic kidney disease (ADPKD) This is the most common type. This is an hereditary condition caused by a faulty gene which is inherited from one parent. Autosomal.

Duchenne muscular dystrophy
The weakness develops gradually. It usually starts to be seen in early childhood. Symptoms are mild at first but increase as the child becomes older. The name Duchenne comes from the doctor who first studied this condition. How common is Duchenne muscular dystrophy. About 1 in 3,500 boys in the UK are born with DMD. There are other types of.

Hereditary spherocytosis
Hereditary spherocytosis (HS) is an inherited condition of red blood cells. The disease can be mild and go unrecognised in some people. In others there may be severe anaemia requiring regular blood transfusions. Some people with hereditary spherocytosis may be offered surgery to remove their spleen. This usually helps the condition, but increases.
