Dwarfism is a condition of people and animals marked by unusually small size or short stature. [1] In humans, it is sometimes defined as an adult height of less than 147 centimetres (4 ft 10 in), regardless of sex; the average adult height among people with dwarfism is 120 centimetres (4 ft).
Achondroplasia is a genetic disorder with an autosomal dominant pattern of inheritance whose primary feature is dwarfism. [3] It is the most common cause of dwarfism [4] and affects about 1 in 27,500 people. [3] In those with the condition, the arms and legs are short, while the torso is typically of normal length. [3]
There is no treatment at this time to promote bone growth in chondrodystrophy patients. Certain types of growth hormone seem to increase the rate of growth during the first year of life/treatment, but have no substantial effect in adult patients. Only a few surgical centers in the world perform, experimentally, leg and arm lengthening procedures.
It is often termed Brachmann de Lange syndrome or Bushy syndrome and is also known as Amsterdam dwarfism. Its exact incidence is unknown, but it is estimated at 1 in 10,000 to 30,000. Its exact incidence is unknown, but it is estimated at 1 in 10,000 to 30,000.

[1] Causes may include genetics, trauma, infections, tumors, or radiation therapy. [2] Genes that may be involved include GH1, GHRHR, or BTK. [3] In a third of cases no cause is apparent. [2]
