L CHD7 gene provides instructions for making a protein called chromodomain helicase DNA binding protein 7. This protein is found in many parts of the body before birth, including the eye, the inner ear, and the brain. In the brain, the CHD7 protein is active in several areas, including a bundle of nerve cells (neurons) called the olfactory bulb that is critical for the perception of odors.

L CHD7 gene provides instructions for making a protein called chromodomain helicase DNA binding protein 7. This protein is found in many parts of the body before birth, including the eye, the inner ear, and the brain. In the brain, the CHD7 protein is active in several areas, including a bundle of nerve cells (neurons) called the olfactory bulb that is critical for the perception of odors.
The CHD7 protein belongs to a family of proteins that are thought to play a role in the organisation of chromatin. Chromatin is the complex of DNA and protein that packages DNA into chromosomes. The CHD7 protein regulates the activity (expression) of several other genes through a process known as chromatin remodeling. The structure of chromatin can be changed (remodeled) to alter how tightly DNA is packaged. When DNA is tightly packed, gene expression is lower than when DNA is loosely packed. Researchers are working to determine which genes the CHD7 protein regulates.

Test genetici
Genetica testing is a type of medical test that identifies changes in chromosomes, genes or proteins. Genetic tests examine a person's DNA in a variety of ways to assess a person's genetic health. They are all designed to identify a particular gene that may cause a genetic disorder. We all have 46 chromosomes in our cells. Chromosomes are made from.

Distrofia muscolare
Non ci sono different types of muscular dystrophy, which vary as to how severe they are, ranging from very mild to severe. The different types also vary as to what age they begin. If muscular dystrophy is suspected, tests can help to make an accurate diagnosis. Other people in the family can also be tested to see if they have a muscular dystrophy.

Emofilia
L blood contains substances called clotting factors that work with platelets to form a clot. When you injure yourself the clot stops you bleeding. Haemophilia is a condition where there is a deficiency of clotting factors, so people with this condition usually have prolonged bleeding. There is no cure but with available treatments most people.
