What is the official name of the CP gene?
The official name of this gene is “ceruloplasmin (ferroxidase).”
CP is the gene's official symbol. The CP gene is also known by other names, listed below.

What is the normal function of the CP gene?
The CP gene provides instructions for making a protein called ceruloplasmin. Ceruloplasmin helps move iron from the organs and tissues of the body into the blood. This protein prepares iron for incorporation into a molecule called transferrin, which transports the iron to red blood cells.
There are two forms of ceruloplasmin. One form, serum ceruloplasmin, is made primarily in the liver. It is involved in transporting iron from most of the body, but is unable to enter the brain. The other form of ceruloplasmin, called the glycosylphosphatidylinositol (GPI)-anchored form, is important for processing iron in the brain and releasing it from brain tissue. This form of ceruloplasmin is made in nervous system cells called glia, which protect and maintain nerve cells (neurons).
How are changes in the CP gene related to health conditions?
Where is the CP gene located?
Cytogenetic Location: 3q23-q25
Molecular Location on chromosome 3: base pairs 148,880,196 to 148,939,831
The CP gene is located on the long (q) arm of chromosome 3 between positions 23 and 25.
More precisely, the CP gene is located from base pair 148,880,196 to base pair 148,939,831 on chromosome 3.
