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

What is the normal function of the PCNT gene?
The PCNT gene provides instructions for making a protein called pericentrin. Within cells, this protein is located in structures called centrosomes. Centrosomes play a role in cell division and the assembly of microtubules. Microtubules are fibers that help cells maintain their shape, assist in the process of cell division, and are essential for the transport of materials within cells.
Pericentrin acts as an anchoring protein, securing proteins to the centrosome that are necessary for its function. Through its interactions with these proteins, pericentrin is involved in the regulation of the cell cycle, which is the cell's way of replicating itself in an organized, step-by-step fashion.
How are changes in the PCNT gene related to health conditions?
Genetics Home Reference provides information about prostate cancer, which is also associated with changes in the PCNT gene.
Where is the PCNT gene located?
Cytogenetic Location: 21q22.3
Molecular Location on chromosome 21: base pairs 46,324,099 to 46,445,768
The PCNT gene is located on the long (q) arm of chromosome 21 at position 22.3.
More precisely, the PCNT gene is located from base pair 46,324,099 to base pair 46,445,768 on chromosome 21.
