HistoryThis section has been translated automatically.

Ekman 1788; Sartorius 1826; Lobstein 1849; Vrolik 1849;

DefinitionThis section has been translated automatically.

Very variable, hereditary connective tissue disease caused by various defects of type 1 collagen, characterized by brittle bones, blue sclerae and numbness.

ClassificationThis section has been translated automatically.

A distinction is made between:

  • OI type I (formerly osteogenesis imperfecta tarda, Lobstein type; manifestation in infancy to early childhood).
  • OI type II
  • OI type III (formerly osteogenesis imperfecta congenita, Vrolik type, or Vrolik syndrome;
  • fractures already in utero)
  • OI type IV
  • OI type V
  • OI type VI
  • OI type VII

Note: Osteogenesis imperfecta/Ehlers-Danlos (OI/EDS) overlap syndrome is a connective tissue disorder characterized by a mutation of the COL1A1 (17q21.33) or COL1A2 (7q21.3) genes involved in the alpha-1 and alpha-2 chains of type 1 collagen synthesis.The clinical spectrum of this clinical entity has features of both osteogenesis imperfecta (bone fragility, long bone fractures, blue sclerae, short stature) and Ehlers-Danlos syndrome (hyperextensibility of joints, soft and hyperextensible skin, abnormal wound healing, easy bruising, vascular fragility).

EtiopathogenesisThis section has been translated automatically.

Autosomal dominant, rare autosomal recessive inheritance. Mutations are present that relate to the alpha-1 or alpha-2 chain of collagen I. Further mutations for various proteins have been detected.

ManifestationThis section has been translated automatically.

Congenital or occurring in early childhood. The prevalence of about 1,15,000 births.

Clinical featuresThis section has been translated automatically.

Blue sclerae, brittle bones with fractures, thin, hyperextensible skin, macular skin atrophies, broadly extended scars, numbness.

Other symptoms include loose joints (joint capsules, ligaments, ligaments)

and

tooth deformities due to dentin formation disorders (dentinogenesis imperfecta).

LaboratoryThis section has been translated automatically.

Hydroxyproline elevation in the urine.

TherapyThis section has been translated automatically.

Not possible.

Progression/forecastThis section has been translated automatically.

Type Vrolik unfavourable, type Lobstein more favourable.
