What is the official name of the CDAN1 gene?
The official name of this gene is “codanin 1.”
CDAN1 is the gene's official symbol. The CDAN1 gene is also known by other names, listed below.

What is the normal function of the CDAN1 gene?
The CDAN1 gene provides instructions for making a protein called codanin-1. Although this protein is active in cells throughout the body, very little is known about its function.
A recent study suggests that codanin-1 is associated with a form of DNA called heterochromatin. Heterochromatin is densely packed DNA that contains few functional genes, but it plays an important role in maintaining the structure of the nucleus (where most of the cell's DNA is located).
Researchers speculate that codanin-1 may be involved in the formation of red blood cells, a process called erythropoiesis. Specifically, this protein may play a key role in the organization of heterochromatin during the division of these developing cells.
How are changes in the CDAN1 gene related to health conditions?
Where is the CDAN1 gene located?
