What is Dwarfism?

Dwarfism is a condition of short stature. Adults 4'10 or under are considered members of the population of people with Dwarfism disorder. There are two types of Dwarfism: disproportionate and proportionate. "Disproportionate dwarfism is characterized by an average-size torso and shorter arms and legs or a shortened trunk with longer limbs. In proportionate dwarfism, the body parts are in proportion but shortened." (Webmd.com Children's Health)

How common is it?

"About around 20,000 to 50,000 Americans live with this genetic condition. A term that many use is "Little People" that refers to those with any growth disorder. It is a way to let others know that even though someone is small, or little, they are people too." (Geneticcounselorofdwarfism.blogspot.com)

The most common type of Dwarfism comes from a dominant gene.
