Medical Definition of achondrogenesis

: a rare disorder of bone and cartilage development in the fetus that is characterized by marked shortening of the limbs with a relatively large head and a short trunk

Note: Infants affected with achondrogenesis typically are stillborn or die shortly after birth. One form of achondrogenesis is inherited as an autosomal recessive trait requiring that both parents pass on a copy of the defective gene on a chromosome other than a sex chromosome. A second form, arising as a spontaneous mutation, is inherited as an autosomal dominant trait requiring that only one parent passes on a copy of the defective gene on a chromosome other than a sex chromosome.
