What is the official name of the APC gene?
The official name of this gene is “adenomatous polyposis coli.”
APC is the gene's official symbol. The APC gene is also known by other names, listed below.

What is the normal function of the APC gene?
The APC gene provides instructions for making the APC protein, which plays a critical role in several cellular processes. The APC protein acts as a tumor suppressor, which means that it keeps cells from growing and dividing too fast or in an uncontrolled way. It helps control how often a cell divides, how it attaches to other cells within a tissue, and whether a cell moves within or away from a tissue. This protein also helps ensure that the number of chromosomes in a cell is correct following cell division. The APC protein accomplishes these tasks mainly through association with other proteins, especially those that are involved in cell attachment and signaling.
One protein with which APC associates is beta-catenin. Beta-catenin helps control the activity (expression) of particular genes and promotes the growth and division (proliferation) of cells and the process by which cells mature to carry out specific functions (differentiation). Beta-catenin also helps cells attach to one another and is important for tissue formation. Association of APC with beta-catenin signals for beta-catenin to be broken down when it is no longer needed.
How are changes in the APC gene related to health conditions?
Genetics Home Reference provides information about primary macronodular adrenal hyperplasia, which is also associated with changes in the APC gene.
Where is the APC gene located?
Cytogenetic Location: 5q21-q22
Molecular Location on chromosome 5: base pairs 112,707,505 to 112,846,239
(Homo sapiens Annotation Release 107, GRCh38.p2) (
The APC gene is located on the long (q) arm of chromosome 5 between positions 21 and 22.
More precisely, the APC gene is located from base pair 112,707,505 to base pair 112,846,239 on chromosome 5.
