CausesDwarfism 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.

Causes 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 SymptomsDwarfism 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.

ComplicationsSome complications:
Small legsSmall legs
Large head compared to the body Smaller organs

Disproportionate Dwarfism Disproportionate Dwarfism is one category of
dwarfism meaning in a way it as the same signs and symptoms.
![Page 10: Kody Prince Karishma Mendes. What is Dwarfism? Dwarfism is characterized by short stature. Technically, that means an adult height of 4 feet 10 inches.](https://reader036.fdocuments.us/reader036/viewer/2022062422/56649e715503460f94b6fb13/html5/thumbnails/10.jpg)
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.
![Page 11: Kody Prince Karishma Mendes. What is Dwarfism? Dwarfism is characterized by short stature. Technically, that means an adult height of 4 feet 10 inches.](https://reader036.fdocuments.us/reader036/viewer/2022062422/56649e715503460f94b6fb13/html5/thumbnails/11.jpg)
Causes 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.
![Page 12: Kody Prince Karishma Mendes. What is Dwarfism? Dwarfism is characterized by short stature. Technically, that means an adult height of 4 feet 10 inches.](https://reader036.fdocuments.us/reader036/viewer/2022062422/56649e715503460f94b6fb13/html5/thumbnails/12.jpg)
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 results from medical
conditions present at birth or appearing in early childhood that limit overall growth and development.
![Page 14: Kody Prince Karishma Mendes. What is Dwarfism? Dwarfism is characterized by short stature. Technically, that means an adult height of 4 feet 10 inches.](https://reader036.fdocuments.us/reader036/viewer/2022062422/56649e715503460f94b6fb13/html5/thumbnails/14.jpg)
Signs and Symptoms Therefore, the head, trunk and limbs are all small,
but they are proportionate to each other.
![Page 15: Kody Prince Karishma Mendes. What is Dwarfism? Dwarfism is characterized by short stature. Technically, that means an adult height of 4 feet 10 inches.](https://reader036.fdocuments.us/reader036/viewer/2022062422/56649e715503460f94b6fb13/html5/thumbnails/15.jpg)
Cause Therefore this disorders affects overall growth, many
of them result in poor development of one or more body systems.
![Page 16: Kody Prince Karishma Mendes. What is Dwarfism? Dwarfism is characterized by short stature. Technically, that means an adult height of 4 feet 10 inches.](https://reader036.fdocuments.us/reader036/viewer/2022062422/56649e715503460f94b6fb13/html5/thumbnails/16.jpg)
Achondroplasia 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.

Causes A person with the disorder may pass along either a
mutated or normal copy to his or her own children.
