What is the official name of the PNPLA2 gene?
The official name of this gene is “patatin-like phospholipase domain containing 2.”
PNPLA2 is the gene's official symbol. The PNPLA2 gene is also known by other names, listed below.

What is the normal function of the PNPLA2 gene?
The PNPLA2 gene provides instructions for making an enzyme called adipose triglyceride lipase (ATGL). The ATGL enzyme plays a role in breaking down fats called triglycerides, which are the main source of stored energy in cells. Triglycerides are the major component of cell structures called lipid droplets (also called adiposomes). The ATGL enzyme is found on the surface of lipid droplets. When activated, the ATGL enzyme breaks down triglycerides to provide energy for the body.
