Genetics and other risk factors Dwarfism is usually the result of a genetic mutation. Children with dwarfism are particularly vulnerable to teasing and ridicule from classmates. Other risk factors for dwarfism include a hormone deficiency or malnutrition. Disproportionate dwarfism The characteristic features of the skull, spine and limbs shared by most forms of disproportionate dwarfism result in some common problems:
This is the most common cause of dwarfism. Unless the brain is directly affected by the underlying disorder, there is little to no chance of mental impairment that can be attributed to dwarfism. Children with dwarfism are particularly vulnerable to teasing and ridicule from classmates. If a pair of achondroplasia alleles are present, the result is fatal. A female inherits an X chromosome from each parent. These types of dwarfism are indirect consequences of the generally unhealthy or malnourished condition of the individual, and not of any specific disease. If this hormone is lacking, stunted or even halted growth may become apparent. Short stature is clinically defined as a height within the lowest 2. Sometimes there is no definitive cause of short stature. Other common attributes of dwarfism such as bowed knees and unusually short fingers can lead to back problems, and difficulty in walking and handling objects. This is a lab test of amniotic fluid from the womb. As a result, someone born with proportionate dwarfism may be able to reach an average height or get close to it. The word "midget" is generally considered an offensive term. In achondroplasia the body's limbs are proportionately shorter than the trunk abdominal area , with a larger head than average and characteristic facial features. The pregnancy may go to full term, but the baby is usually much smaller than average. Most occurrences of dwarfism result from a random genetic mutation in either the father's sperm or the mother's egg rather than from either parent's complete genetic makeup. Because these disorders affect overall growth, many of them result in poor development of one or more body systems. Disproportionate dwarfism This is the most common kind of dwarfism. In societies where poor nutrition is widespread, the average height of the population may be reduced below its genetic potential by the lack of proper nutrition. At birth, sometimes the appearance of a newborn may be enough to make a diagnosis of dwarfism. Request an Appointment at Mayo Clinic Causes Most dwarfism-related conditions are genetic disorders, but the causes of some disorders are unknown. Other causes Other causes of dwarfism include other genetic disorders, deficiencies in other hormones or poor nutrition. Children with dwarfism are particularly vulnerable to teasing and ridicule from classmates. Children with this disorder may grow slowly and puberty may be delayed by several years or indefinitely. Those with growth hormone issues tend to be proportionate.
