==Signs and symptoms== Individuals affected by this disorder appear normal at birth. As the infant grows, however, their arms and legs do not develop properly, and their body becomes thicker and shorter than normal. The following are characteristics consistent with this condition: Brachydactyly Short stature Micromelia Skeletal dysplasia Abnormality of femur
