Metatrophic Dysplasia



- See: Kniest Dysplasia:

- Discussion:
  - rare skeletal dysplasia characterized by change in body proportions w/
      growth;
  - because of the short limbs and relatively long trunk during infancy,
      this condition often has been confused with achrondroplasia;
  - unlike pts with achrondroplasia, the head and face appear normal;
  - severe kyphoscoliosis may develop, w/ a marked shortening of trunk
      and an apparent reversal of body proportions;
  - curves are severe and rigid;
- Diff Dx:
  - Morquio's
  - Achondroplasia
