Omodysplasia 2
Other names: Omodysplasia, Autosomal dominant[1]
Omodysplasia 2 is inherited in an autosomal dominant manner.

Omodysplasia type 2 is a very rare genetic disorder characterised by abnormalities in the skull, long bones and genitourinary system.

Signs and symptoms

These can be grouped under those evident in the skull/face, the long bones and the genitourinary system

  • Skull
    • Anteverted nostrils
    • Bifid nasal tip
    • Depressed nasal bridge
    • Fontal bossing
    • Long philtrum
    • Low set ears
  • Long bones
    • Short first metacarpal
    • Short humerus
  • Genitourinary
    • Genitourinary hypoplasia

Genetics

This condition is inherited in an autosomal dominant fashion.

Mutations in the Frizzled Class Receptor 2 (FZD2) gene have been associated with this condition.[2]

Diagnosis

a) Large forehead, hypertelorism, cleft lip b) limited extension left elbow c) short first metacarpal d)bilateral radial head dislocation and proximal radioulnar joint disatasis in chest X‐ray e)normal hip radiography

The diagnosis of Omodysplasia 2 is done via the following :[3]

  • Clinical features
  • Genetic test

Differential diagnosis

Treatment

There is no currently known treatment for this condition.

History

This condition was first described by Maroteaux et al in 1989.[4]
