L SLC45A2 gene (also called MATP) provides instructions for making a protein that is located in specialized cells called melanocytes. These cells produce a pigment called melanin, which is the substance that gives skin, hair, and eyes their colour. Melanin is also found in the light-sensitive tissue at the back of the eye (the retina), where it plays a role in normal vision.

L SLC45A2 gene (also called MATP) provides instructions for making a protein that is located in specialized cells called melanocytes. These cells produce a pigment called melanin, which is the substance that gives skin, hair, and eyes their colour. Melanin is also found in the light-sensitive tissue at the back of the eye (the retina), where it plays a role in normal vision.
Although the exact function of the SLC45A2 protein is unknown, it is likely involved in the production of melanin. This protein probably transports molecules necessary for the normal function of melanosomes, which are the structures in melanocytes where melanin is produced. Studies suggest that certain common variations (polymorphisms) in the SLC45A2 gene may be associated with normal differences in skin, hair, and eye coloring.

Emocromatosi
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.

Sferocitosi ereditaria
Hereditary spherocytosis (HS) è 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.

la malattia di Wilson
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. la malattia di Wilson è an autosomal recessive disorder. This means that, in order to develop Wilson's disease, two abnormal ATP7B genes must be.

distrofia muscolare di Duchenne
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.
