Dwarfism is short stature resulting from a particular medical condition. It is sometimes defined as an adult height of less than 4 feet 10 inches (147 cm), although this definition is problematic because short stature in itself is not a disorder.
Most dwarfism-related conditions are genetic disorders, but the causes of some disorders are unknown. Most occurrences of dwarfism result from a random genetic mutation in either the father's sperm or the mother's egg rather than being in either parent's complete genetic makeup.
There are more than 200 various medical conditions associated with dwarfism. Therefore, its symptoms may vary according to the spectrum of disorders. Generally, dwarfism is categorized as disproportionate and proportionate. In case of disproportionate dwarfism, the body size is not in proper proportion. Some body parts are small, while others are normal or above size. In proportionate dwarfism, on the other hand, the size of whole body is smaller than average, but all body parts are small to the same degree.
