What is the official name of the ALPL gene?
The official name of this gene is “alkaline phosphatase, liver/bone/kidney.”
ALPL is the gene's official symbol. The ALPL gene is also known by other names, listed below.

What is the normal function of the ALPL gene?
The ALPL gene provides instructions for making an enzyme called alkaline phosphatase. This enzyme plays an important role in the growth and development of bones and teeth. It is also active in many other tissues, particularly in the liver and kidneys. This enzyme acts as a phosphatase, which means that it removes clusters of oxygen and phosphorus atoms (phosphate groups) from other molecules.
Alkaline phosphatase is essential for the process of mineralization, in which minerals such as calcium and phosphorus are deposited in developing bones and teeth. Mineralization is critical for the formation of bones that are strong and rigid and teeth that can withstand chewing and grinding.
How are changes in the ALPL gene related to health conditions?
Where is the ALPL gene located?
