It is suggested that the differential diagnosis between thanatophoric dwarfism and achondrogenesis can be established unequivocally on radiographic grounds, as can the differentiation of these two lethal skeletal dysplasias from classic achondroplasia. Early Fatal types of dwarfism are uncommon with most being due to spontaneous or new (denovo) mutations in genes which control growth and other vital organ functions. A month later, the Kupers learned that their baby, a girl, had a genetic disorder called thanatophoric dysplasia, a very rare form of dwarfism, diagnosed in one in 50,000 births.
