The SLC26A2 gene provides instructions for making a protein that transports charged molecules (ions), particularly sulfate ions, across cell membranes. This protein appears to be active in many of the body's tissues, including developing cartilage. Cartilage is a tough, flexible tissue that makes up much of the skeleton during early development. Most cartilage is later converted to bone, except for the cartilage that continues to cover and protect the ends of bones and is present in the nose and external ears.

The SLC26A2 gene provides instructions for making a protein that transports charged molecules (ions), particularly sulfate ions, across cell membranes. This protein appears to be active in many of the body's tissues, including developing cartilage. Cartilage is a tough, flexible tissue that makes up much of the skeleton during early development. Most cartilage is later converted to bone, except for the cartilage that continues to cover and protect the ends of bones and is present in the nose and external ears.
Cartilage cells use sulfate ions transported by the SLC26A2 protein to build molecules called proteoglycans. These molecules, which each consist of several sugars attached to a protein, help give cartilage its rubbery, gel-like structure. Because sulfate ions are required to make proteoglycans, the transport activity of the SLC26A2 protein is essential for normal cartilage formation.

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 is an hereditary condition caused by a faulty gene which is inherited from one parent. Autosomal recessive polycystic kidney disease (ARPKD) This is a rare condition which affects about 1 in 20,000 people. Although people with PKD often develop kidney failure (end-stage kidney disease) between ages 55 to 65 years, some people with PKD have a.

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.

Cystic fibrosis
What causes cystic fibrosis. Cystic fibrosis is a genetic disorder. A genetic disorder is one that can be passed on from your parents through your genes. How is cystic fibrosis inherited. 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.

Wilson's disease
When the copper storage capacity of the liver cells is exhausted, the copper spills into the bloodstream and deposits copper in other parts of the body, mainly the brain. How is Wilson's disease inherited. Wilson's disease is an autosomal recessive disorder. This means that, in order to develop Wilson's disease, two abnormal ATP7B genes must be.

Duchenne muscular dystrophy
Each person inherits a set of genes from their father and another set from their mother. The genes have been copied from the parents' cells into the child's cells. Genes are found on 'chromosomes', rather like houses on a street. The DMD gene is located on a chromosome called the X chromosome. Boys have one X chromosome and one Y chromosome; girls.
