What is the official name of the PLOD1 gene?
The official name of this gene is “procollagen-lysine, 2-oxoglutarate 5-dioxygenase 1.”
PLOD1 is the gene's official symbol. The PLOD1 gene is also known by other names, listed below.

What is the normal function of the PLOD1 gene?
The PLOD1 gene provides instructions for making an enzyme called lysyl hydroxylase 1. This enzyme modifies an amino acid called lysine, which is one of the building blocks used to make proteins. Specifically, lysyl hydroxylase 1 converts lysine to a similar molecule, hydroxylysine, through a chemical reaction called hydroxylation. Hydroxylysine is commonly found in collagens, which are complex molecules that provide strength and support to many body tissues.
Hydroxylysine is essential for collagen molecules to form stable interactions, called cross-links, with one another in the spaces between cells. The cross-links result in the formation of very strong collagen fibers.
