Thanatophoric Dysplasia


CR – Narrow chest with short ribs, flat vertebral bodies, short ilia with horizontal inferior portions, small sciatic notch, short and bowed long bones, and increased craniofacial ratio.


Thanatophoric dysplasia is an autosomal dominant disorder caused by a mutation in the FGFR3 (fibroblast growth factor receptor) gene. This dysplasia is characterized by respiratory insufficiency at birth. Few infants survive unassisted; those that survive require ventilatory support, have mental deficiencies and short stature.
