Treating Achondroplastic Dwarfism

There is no cure for achondroplastic dwarfism. However, there are options that will treat the signs, symptoms, and health conditions that occur as a result of this disorder (see Treatment for Achondroplastic Dwarfism).

How Common Is It?

Achondroplastic dwarfism is the most common type of short-limbed dwarfism. This condition affects 1 in 15,000 to 40,000 births.

What Is the Prognosis?

The prognosis for people with achondroplastic dwarfism depends on the severity of their condition. In 2 percent to 5 percent of all cases, newborns do not survive more than 12 months after birth. However, such cases are severe and not as common. Most people with this condition should expect to live a normal lifespan and have normal intelligence.
