The COLQ gene provides instructions for making a protein called acetylcholinesterase collagenic tail peptide. This protein plays an important role in the neuromuscular junction, which is the area between nerve cells and muscle cells where signals are passed on to trigger muscle movement.
Normal function
The COLQ gene provides instructions for making a protein called acetylcholinesterase collagenic tail peptide. This protein plays an important role in the neuromuscular junction, which is the area between nerve cells and muscle cells where signals are passed on to trigger muscle movement.
The acetylcholinesterase collagenic tail peptide anchors another protein called acetylcholinesterase to the muscle cell at the neuromuscular junction. The acetylcholinesterase collagenic tail peptide is made up of three identical parts (subunits). Each subunit attaches (binds) to a bundle of four acetylcholinesterase proteins. Acetylcholinesterase plays a role in regulating the signaling between nerve cells and muscle cells by breaking down the signaling protein acetylcholine.

Dupuytren's contracture
Injection treatment Steroid injections may be beneficial for some people with painful nodules and cords in the palm, but only if there is no contracture or loss of function. In some cases, injection of a collagenase (which dissolves collagen), or of a biologic drug (which suppresses the immune system) may be helpful. These last two are not.

Pelvic organ prolapse
However, with new advances in surgical techniques, including keyhole (laparoscopic) surgery, this is becoming less of a problem. Other risk factors Very rarely, pelvic organ prolapse can occur because of Ehlers-Danlos syndrome (EDS), a congenital problem (a problem that someone is born with) that causes deficiency, in the body, of a substance.
