Involvement in diseasei

Caffey disease (CAFFD)1 Publication
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionCharacterized by an infantile episode of massive subperiosteal new bone formation that typically involves the diaphyses of the long bones, mandible, and clavicles. The involved bones may also appear inflamed, with painful swelling and systemic fever often accompanying the illness. The bone changes usually begin before 5 months of age and resolve before 2 years of age.

Osteogenesis imperfecta 1 (OI1)12 Publications
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionAn autosomal dominant form of osteogenesis imperfecta, a connective tissue disorder characterized by low bone mass, bone fragility and susceptibility to fractures after minimal trauma. Disease severity ranges from very mild forms without fractures to intrauterine fractures and perinatal lethality. Extraskeletal manifestations, which affect a variable number of patients, are dentinogenesis imperfecta, hearing loss, and blue sclerae. OI1 is a non-deforming form with normal height or mild short stature, and no dentinogenesis imperfecta.

Osteogenesis imperfecta 2 (OI2)39 Publications
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionAn autosomal dominant form of osteogenesis imperfecta, a connective tissue disorder characterized by low bone mass, bone fragility and susceptibility to fractures after minimal trauma. Disease severity ranges from very mild forms without fractures to intrauterine fractures and perinatal lethality. Extraskeletal manifestations, which affect a variable number of patients, are dentinogenesis imperfecta, hearing loss, and blue sclerae. OI2 is characterized by bone fragility, with many perinatal fractures, severe bowing of long bones, undermineralization, and death in the perinatal period due to respiratory insufficiency.

Disease descriptionAn autosomal dominant form of osteogenesis imperfecta, a connective tissue disorder characterized by low bone mass, bone fragility and susceptibility to fractures after minimal trauma. Disease severity ranges from very mild forms without fractures to intrauterine fractures and perinatal lethality.

Osteoporosis (OSTEOP)2 Publications
Disease susceptibility is associated with variations affecting the gene represented in this entry.
Disease descriptionA systemic skeletal disorder characterized by decreased bone mass and deterioration of bone microarchitecture without alteration in the composition of bone. The result is fragile bones and an increased risk of fractures, even after minimal trauma. Osteoporosis is a chronic condition of multifactorial etiology and is usually clinically silent until a fracture occurs.

Post-translational modificationi

Contains mostly 4-hydroxyproline. Proline residues at the third position of the tripeptide repeating unit (G-X-Y) are hydroxylated in some or all of the chains.1 Publication
Contains 3-hydroxyproline at a few sites. This modification occurs on the first proline residue in the sequence motif Gly-Pro-Hyp, where Hyp is 4-hydroxyproline.By similarity
Lysine residues at the third position of the tripeptide repeating unit (G-X-Y) are 5-hydroxylated in some or all of the chains.1 Publication
O-glycosylated on hydroxylated lysine residues. The O-linked glycan consists of a Glc-Gal disaccharide.1 Publication
