Recessive mutations in FKBP10 at 17q21.2, encoding FKBP65, cause both osteogenesis imperfecta (OI) and Bruck syndrome (OI plus congenital contractures).
PLOD2 and FKBP10 are genes mutated in Bruck syndrome (BS), a condition resembling osteogenesis imperfecta (OI), but that is also typically associated with congenital joint contractures.
Two follow up reports found FKBP10 mutations to be associated with Bruck syndrome type 1, a rare disorder characterized by congenital contractures and bone fragility.
