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...
