Paget disease of bone-5 is an autosomal recessive, juvenile-onset form of Paget disease, a disorder of the skeleton resulting from abnormal bone resorption and formation. Clinical manifestations include short stature, progressive long bone deformities, fractures, vertebral collapse, skull enlargement, and hyperostosis with progressive deafness. There is phenotypic variability, with some patients presenting in infancy, while others present later in childhood (summary by Naot et al., 2014).

- Disease or Syndrome
Hydroxyproline is an imino acid normally present in human plasma. It is derived primarily from endogenous collagen turnover and the breakdown of dietary collagen. The finding of elevated (5- to 10-fold increase from the normal of less than 50 micromoles) serum hydroxyproline is thought to be an inherited defect in the catabolism of hydroxyproline.
