Thanatophoric dysplasia is a severe skeletal disorder that is lethal in the neonatal period. Two clinically defined TD subtypes have been classified: type I (TDI), characterized by micromelia with bowed femurs and, occasionally, by the presence of cloverleaf skull deformity of varying severity and type II (TDII), characterized by micromelia with straight femurs and a moderate to severe cloverleaf skull deformity.
