Hypochrondroplasia is a genetic disorder characterized by small stature and disproportionately short arms, legs, hands, and feet (short-limbed dwarfism). Short stature often is not recognized until early to mid childhood or, in some cases, as late as adulthood. In those with the disorder, bowing of the legs typically develops during early childhood but often improves spontaneously with age. Some affected individuals may also have an abnormally large head (macrocephaly), a relatively prominent forehead, and/or other physical abnormalities associated with the disorder. In addition, in about 10 percent of cases, mild mental retardation may be present.
In some cases, hypochondroplasia appears to occur randomly for unknown reasons (sporadically) with no apparent family history. In other instances, the disorder is familial with autosomal dominant inheritance.
