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
