It is one of the group of disorders that are collectively called chondrodystrophies.
Achondroplasia is the most common type of dwarfism.
Achondroplasia is inherited as an autosomal dominant trait. Genetic counseling may be helpful for prospective parents when one or both have achondroplasia. Because achondroplasia arises as a spontaneous mutation, absolute prevention is not possible. A family history of achondroplasia should alert parents to the possibility of having an affected child. Typical appearance of achondroplastic dwarfism is apparent at birth.
