APOA2 gene

The APOA2 gene (APOA2 stands for: Apolipoprotein A2) is a protein coding gene located on chromosome 1q23.3.

This gene encodes apolipoprotein (apo-) A-2, the second most abundant protein of high-density lipoprotein particles. The protein occurs in plasma as a monomer, homodimer, or heterodimer with apolipoprotein D.

Diseases associated with APOA2 include:

• Hypercholesterolemia, familial, 1

and

• AapoA2 amyloidosis (apolipoprotein A2 amyloidosis; see also apolipoprotein A1 amyloidosis).

The encoded protein May stabilize high density lipoprotein (HDL) structure through its association with lipids and affect HDL metabolism.
