what is dwarfism
What is Dwarfism?
  • Dwarfism is characterized by short stature. Technically, that means an adult height of 4 feet 10 inches or under, according to the advocacy group Little People of America.



  • Dwarfism can be caused by any one of more than 200 conditions, most of which are genetic. The most common type, accounting for 70% of all cases of short stature, is called Achondroplasia.
  • Dwarfism causes mostly occurs in families where both parents are an average height. In fact, 4 out of 5 of children with Achondroplasia are born to average-size parents.
signs and symptoms
Signs and Symptoms
  • Dwarfism symptoms other than short stature vary considerably across the spectrum of disorders. In general, the disorders are divided into two broad categories:
  • Disproportionate dwarfism.
  • Proportionate dwarfism.
signs and symptoms1
Signs and Symptoms

There are some symptoms like:

  • Poor growth
  • Failure to thrive
  • Short stature
  • Short bones
  • Short arms
  • Short legs
diagnostic t est treatments
Diagnostic Test Treatments
  • Measurements (when young generally check up)
  • History (look at the past medical history in your family)
  • MRI (scan for abnormal formalities on the skull and other parts)

Some complications:

Small legs

Small legs

Large head compared to the body

Smaller organs

disproportionate dwarfism
Disproportionate Dwarfism
  • Disproportionate Dwarfism is one category of dwarfism meaning in a way it as the same signs and symptoms.
disproportionate dwarfism1
Disproportionate Dwarfism
  • Usually a person has an average-size trunk and very short limbs, but some people may have a very short trunk and shortened limbs. Some characteristic of this disorders is the head being disproportionately large compared to the body.
  • The most common cause of dwarfism is a disorder called achondroplasia, which causes disproportionately short stature. the other rare disorder that causes disproportionate dwarfism is called spondyloepiphyseal dysplasia congenita.
signs and symptoms2
Signs and Symptoms
  • An average-size trunk
  • Short arms and legs, with particularly short upper arms and upper legs
  • Short fingers, often with a wide separation between the middle and ring fingers
  • Limited mobility at the elbows
proportionate dwarfism
Proportionate Dwarfism
  • Proportionate dwarfism results from medical conditions present at birth or appearing in early childhood that limit overall growth and development.
signs and symptoms3
Signs and Symptoms
  • Therefore, the head, trunk and limbs are all small, but they are proportionate to each other.
  • Therefore this disorders affects overall growth, many of them result in poor development of one or more body systems.
  • A person with Achondroplasia and with two average-size parents received one mutated copy of the gene associated with the disorder and one normal copy of the gene.
  • A person with the disorder may pass along either a mutated or normal copy to his or her own children.
turner syndrome
Turner Syndrome
  • Turner syndrome occurs because of a random deletion or severe alteration of an X chromosome either in the sperm or egg.
  • The X chromosome is one of two chromosomes that determine the sex of a person.


  • A girl with Turner syndrome has only one fully functioning copy of the female sex chromosome rather than two.
signs symptoms
Signs Symptoms
  • Absent or incomplete development at puberty, including sparse pubic hair and small breasts
  • Broad, flat chest shaped like a shield
  • Drooping eyelids
  • Dry eyes
  • No periods (absent menstruation)
  • Short height
  • Vaginal dryness, can lead to painful intercourse
