   Dwarfism is a typically pathological condition in which the physical size of a person, animal, or plant is well below normal. This article primarily discusses dwarfism in human beings.
   SymptomsThe distinguishing symptom of dwarfism is abnormally and significantly shorter stature with respect to other persons in the same age cohort, and especially in adults who have reached their final heights. Many conditions that cause dwarfism also have other distinctive symptoms.
   TopCausesThere are approximately 200 different types of dwarfism. [1]
   Of the hundreds of causes of dwarfism in humans, most are genetic, and most involve single-gene variations that affect the structure or metabolism of bone, cartilage, or connective tissue. This class of disorder is referred to by physicians as skeletal dysplasia. Chondrodystrophy, chondrodysplasia, osteochondrodystrophy are also used (fairly interchangeably) in the medical literature to refer to most of these conditions. In some conditions, the bones are the primary affected body part, and the person is otherwise healthy. In others, the genetic difference affects other body systems, causing unusual features or other major problems. Achondroplasia is one of the most common and perhaps the most easily recognized skeletal dysplasia. It affects approximately 1 in 40,000 children, both males and females, as it is due to a mutation of an autosomal gene.
   Some people are naturally short, because they have inherited small stature from their parents and ancestors. Apart from their unusually short stature, they are normal in every other way. Relatively few people in this category are short enough to be considered dwarfs.
   TopDiagnosis (((( Unusually short stature for a child’s age is usually what brings the child to medical attention.)))) Skeletal dysplasia ("dwarfism") is usually suspected because of obvious physical features (e.g., unusual configuration of face or shape of skull), because of an obviously affected parent, or because body measurements (arm span, upper to lower segment ratio) indicate disproportion. Bone x-rays are often the key to diagnosis of a specific skeletal dysplasia. Most children with suspected skeletal dysplasias will be referred to a genetics clinic for diagnostic confirmation and genetic counselling. (See External links, below, for a list of American referral centers with special expertise in skeletal dysplasias.) In the last decade, genetic tests for some of the specific disorders have become available.
   During the initial medical evaluation for shortness, the absence of disproportion and the other clues above usually indicates other causes than bone dysplasias. Extreme shortness with completely normal proportions sometimes indicates growth hormone deficiency (pituitary dwarfism).
   Short stature alone, in the absence of any other abnormalities, may simply be genetic, particularly if a person is born into a family of people who are relatively short.
