What causes Toulouse Lautrec syndrome?

What causes it? A mutation of the gene that codes the enzyme cathepsin K (CTSK) on chromosome 1q21 causes PYCD. Cathepsin K plays a key role in bone remodeling. In particular, it breaks down collagen, a protein that acts as scaffolding to support minerals such as calcium and phosphate in bones.
