Medical Information

There are over 200 conditions that cause dwarfism. We list just a few below.

For more information about these conditions or others that cause dwarfism, go to the Little People of America medical resource centre.

In addition, the Alfred I. DuPont Hospital for Children/Nemours website contains information on some of these conditions under the skeletal dysplasia section (you'll find the actual links to the pages for the specific conditions in the left-hand sidebar on this page on the Nemours website, though we have included the links below), in a well-laid out, easy to read format.

  • Achondroplasia (in Nemours)
  • Acromesomelic dysplasia
  • Campomelic dysplasia (in Nemours)
  • Cartilage hair hypoplasia (CHH), also known as metaphyseal chondrodysplasia, McKusick type (in Nemours)
  • Conradi–Hunermann syndrome
  • Craniopharyngioma (in e-Medicine, updated June 2008, and MedlinePlus)
  • Desbuquois syndrome
  • Diastrophic dysplasia (in Nemours)
  • Ellis–van Creveld syndrome (in Nemours)
  • Geleophysic dysplasia – rare, autosomal recessive disorder thought to be a lysosomal storage disorder. Characterised by 'happy natured' facial expression, short stature with short limbs, brachydactyly and joint contractures. Newly published research may suggest genes/biochemical pathways involved (go to Research)
  • Hypochondroplasia (in Nemours)
  • Hypopituitarism
  • Hypothyroidism that develops before birth
  • Kniest syndrome (in Nemours)
  • Larsen syndrome
  • Metaphyseal chondrodysplasia, Jansen type
  • Morquio syndrome (MPS IV) (in Nemours)
  • Multiple epiphyseal dysplasia (MED) (in Nemours)
  • Osteogenesis imperfecta (OI)
  • Pituitary dwarfism
  • Primordial dwarfism (microcephalic osteodysplastic primordial dwarfism, MOPD) (in Nemours)
  • Pseudoachondroplasia (in Nemours)
  • Russell–Silver syndrome
  • Spondyloepimetaphyseal dysplasia, Studwick type (SEMD)
  • Spondyloepiphyseal dysplasia (SED), many types (in Nemours)
  • Spondylometaphyseal dysplasia (SMD), corner fracture type (or any other type)
  • Turner syndrome

In addition, certain chronic diseases may affect growth, such as congenital heart disease, kidney diseases, asthma, sickle cell anaemia, thalassemia, juvenile rheumatoid arthritis, and diabetes.
