Omodysplasia 2

From WikiMD's Wellness Encyclopedia


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

Clinical features[edit | edit source]

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[edit | edit source]

This condition is inherited in an autosomal dominant fashion.

Mutations in the Frizzled Class Receptor 2 (FZD2) gene have been associated with this condition.[1]

Diagnosis[edit | edit source]

Differential diagnosis[edit | edit source]

Robinow syndrome

Treatment[edit | edit source]

There is no currently known treatment for this condition.

History[edit | edit source]
