What causes prolidase deficiency?

Prolidase deficiency is a genetic disorder caused by a mutation of a gene called peptidase D (PEPD). The PEPD gene is located on chromosome 19 and it has the information on how to make the enzyme prolidase, which has a role breaking and recycling proteins, including collagen.[1][2] Collagen is a protein widely distributed in the body and provides structural support (like a skeleton) to internal organs and connective tissues such as skin, bones,tendons, and ligaments.
