What is Metatropic Dysplasia

Metatropic Dysplasia is a very rare form of dwarfism. There are just over 80 known cases of Metatropic Dysplasia worldwide. Babies are born with a long trunk and short arms and legs. Most literature you read will mention that they also have a tail like appendage. This is not true for all cases. It tends to be true for more extreme cases.

Due to progressive kyphoscoliosis, the trunk will begin to look shorter and the arms will begin to become more proportionate as they grow. There are several bone deformities in the legs, arms, spine, hips, and joints. The Kyphoscoliosis can be very rapid and aggressive causing a very severe curve. This can cause breathing problems later in life as well as spinal stenosis (narrowing of the spinal column).
If you are a parent of a child who was recently diagnosed with this condition or they have physical characteristics similar to the ones described above, its important to note that there are varying degrees of severity with MD in kids.  Of the people we know with this condition, not all have had the same experience.
