Der SYNGAP1 gene provides instructions for making a protein, called SynGAP, that plays an important role in nerve cells in the brain. SynGAP is found at the junctions between nerve cells (synapses) where cell-to-cell communication takes place. Connected nerve cells act as the "wiring" in the circuitry of the brain. Synapses are able to change and adapt over time, rewiring brain circuits, which is critical for learning and memory. SynGAP helps regulate synapse adaptations and promotes proper brain wiring. The protein's function is particularly important during a critical period of early brain development that affects future cognitive ability.

Das Immunsystem
This leaflet gives a brief overview of Immunsystems and how it works. A person with a weak immune system might have difficulty fighting off infections. In autoimmune diseases the body is unable to tell what is its own and what is foreign, so it attacks itself. Autoimmune diseases can attack any part of the body - eg, type 1 diabetes.

Leberfunktionstests
Leberfunktionstests are a set of blood tests commonly done to check on the health of your liver. Changes in liver function tests give a clue as to whether your liver is under strain, inflamed, infected or diseased, and how badly. The pattern of the liver function tests can give a clue to the cause and can allow early detection of unsuspected.

Nephrotisches Syndrom
Nephrotic syndrome is a condition where the 'filters' in the kidney become 'leaky' and large amounts of protein leak from the blood into the urine. The main symptom is fluid retention (oedema) which is mainly due to the low protein level in the blood. Various diseases can cause nephrotic syndrome, some more serious than others. Nephrotic syndrome.
