Pycnodysostosis () is a lysosomal storage disease of the bone caused by a mutation in the gene that codes the enzyme cathepsin K. It is also known as PKND and PYCD.

== History == The disease was first described by Maroteaux and Lamy in 1962 at which time it was defined by the following characteristics: dwarfism; osteopetrosis; partial agenesis of the terminal digits of the hands and feet; cranial anomalies, such as persistence of fontanelles and failure of closure of cranial sutures; frontal and occipital bossing; and hypoplasia of the angle of the mandible. The defective gene responsible for the disease was discovered in 1996. The French painter Henri de Toulouse-Lautrec (1864–1901), whose parents were first cousins, is believed to have had the disease.
