A JAG1 gene provides instructions for making a protein called Jagged-1, which is involved in an important pathway by which cells can signal to each other. The Jagged-1 protein is inserted into the membranes of certain cells. It connects with other proteins called Notch receptors, which are bound to the membranes of adjacent cells. These proteins fit together like a lock and its key. When a connection is made between the Jagged-1 and Notch proteins, it launches a series of signaling reactions (Notch signaling) affecting cell functions. Notch signaling controls how certain types of cells develop in a growing embryo, especially cells destined to be part of the heart, liver, eyes, ears, and spinal column. The Jagged-1 protein continues to play a role throughout life in the development of new blood cells.

Traço falciforme
If you inherit a gene from one of your parents, called a sickle cell gene, you have a condition called sickle cell trait. If you inherit a sickle cell gene from both parents, you get a double dose of the sickle cell gene. This causes a condition called sickle cell disease (SCD). What is sickle cell trait. Sickle cell trait means having one gene.

Morte súbita inesperada na epilepsia
Sudden unexpected death occurs in a small number of people who have epilepsy. People most at risk are those with severe frequent seizures. Preventing seizures as much as possible with treatment may reduce the risk of sudden death. A support group may be helpful if you are bereaved by an unexpected death of a loved one.
