Q77: Osteochondrodysplasia with defects of growth of tubular bones and spine
Q77.5: Dystrophic dysplasia
While developing in the womb, many different types of tissue develop in the body. The organs and body parts develop out of the various types of tissue. There is cartilage in various parts of the body. For example, the bones are covered by cartilage at the joints. The bones also develop from cartilage tissue while in the womb. If the cartilage tissue fails to develop properly, various deformities may occur.
With this condition, for example, the arms and legs may be shorter than usual. The feet may point inwards in an unusual position, and the thumbs may be splayed. Blister-type swellings may also develop on the ears during the first days after the birth. With this condition the joints may also be changed.
This developmental disorder has arisen due to a change in the genetic information. Changes to the genetic information can be inherited within the family. Other family members may therefore also be affected.
