Background: Ehlers–Danlos syndrome (EDS) comprises a group of inherited connective tissue disorders, caused by various defects in the biosynthesis or secretion of fibrillar collagens. As collagen represents a major constituent of the bone matrix as well as of tendons and muscle, bone strength in EDS patients might be impaired both via direct and indirect pathways. Although decreased muscle strength, decreased areal bone mineral density (BMD) and increased fracture risk ha...

Bruck syndrome, a disorder caused by bi-allelic mutations in either PLOD2 or FKBP10, is characterized by flexion contractures and bone fractures and shows strong clinical overlap with the brittle bone disease Osteogenesis Imperfecta. PLOD2 encodes the Lysyl hydroxylase 2 (LH2) enzyme, which is responsible for the hydroxylation of lysine residues in the type-I collagen telopeptides. This hydroxylation directs cross-linking of the collagen fibrils in t...
