The FAM20A gene provides instructions for making a protein that is found in cells throughout the body. The FAM20A protein plays a role in 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 strong and rigid bones. It is also involved in building tooth enamel, which is the hard, white material that forms the protective outer layer of each tooth. Enamel strengthens teeth so they can withstand chewing and grinding. The FAM20A protein also plays a role in regulating the levels of calcium in the kidneys.
