The DOK7 gene provides instructions for making a protein that helps form connections between nerve cells and muscle cells at the neuromuscular junction. The neuromuscular junction is the area between nerve cells and muscle cells where signals are passed on to trigger muscle movement.
Normal function
The DOK7 gene provides instructions for making a protein that helps form connections between nerve cells and muscle cells at the neuromuscular junction. The neuromuscular junction is the area between nerve cells and muscle cells where signals are passed on to trigger muscle movement.
The Dok-7 protein participates in turning on (activating) a protein called MuSK that helps organize the various proteins that are important for developing and maintaining the neuromuscular junction. In particular, MuSK is involved in gathering a protein called the acetylcholine receptor (AChR) on the surface of the muscle cells at the neuromuscular junction. The AChR protein is critical for signaling between nerve and muscle cells.

Proteinuria
Proteins are molecules that are found in almost every part of the body, including in the blood. The kidneys normally have a filter which stops protein from entering the urine, except in very tiny amounts; however, kidney problems can cause higher levels of protein to be found in the urine. What is proteinuria. Proteinuria means that there is an.

Nephrotic syndrome
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. Treatment and.
