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 a particular amino acid called lysine, which is one of the building blocks used to make proteins. Specifically, lysyl hydroxylase 1 adds a single oxygen atom to a hydrogen atom to create a charged molecule called a hydroxyl group. Hydroxyl groups attach to some of the lysines in collagen-like proteins. Collagens are complex molecules that provide strength, support, and elasticity (the ability to stretch) to many body tissues.
The addition of hydroxyl groups is essential for collagen molecules to form stable interactions, called cross-links, with one another. Cross-links between these molecules allow collagen to form networks of strong, slender fibrils, which are an important part of the normal structure of connective tissue (the tissue that binds and supports the body's muscles, ligaments, organs, and skin).
