 * What is Cri-Du-Chat Syndrome?! **
 * Cri Du Chat Synrome is rare. The name is French for "cry of the cat," this is because children born with this have a really high pitched cry. Abnormal development of the larynx causes the high cat like cry. This usually become less noticable as the baby gets older, after age two this becomes very difficult for doctors to diagnose. Other names for this syndrome are chromosome 5p deletion syndrome, 5p minus syndrome, cat cry syndrome. ||
 * What Causes Cri-Du-Chat?! **
 * Cri Du Chat is caused by the deletion of part of the chromosome. In most cases the cell usually breaks while the sperm or egg cell is developing. When this gamete is fertalized cri-du-chat is developed. This break is not in the parents chromosome and is so rare that if the parent was to have another child it very unlikely for it to happen again. This can be inherited from the parents, however, most cases of cri-du-chat are not inherited. || [[image:cri-du-chat_diagram.gif width="267" height="93"]] ||

The features of someone with cri-du-chat are very distinctive features.They may have a small head, an unusually round face, small chin, eyes set far apart, skin folds over the eyes, and a small bridge of the nose. Along with the physical features that come from cri-du-chat are the mental and health issues from it. A few children with cri-du-chat have heart defects, muscular or skeletal problems, hearing or sight problems, or poor muscle tone. Children with cri-du-chat usually have a problem talking and walking correctly. Behavioral problems and sever mental retardation may also occur. Life expectancy is normal as long as no other critcal conditions exsist. ||
 * What are Symptoms of Cri-Du-Chat?! **
 * [[image:criduchat.jpg width="282" height="327"]] || Babies with Cri-Du-Chat are usually born with low birth weight. They may also have respritory problems. Often the larnyx doesn't develop correctly, and this is what causes the high pitched cat cry.

Cri-Du-Chat and other chromosomal errors can also be checked before the baby is born. This can be done with chronic villi sampling (sample of tissue from outside of sac), or amniocentesis (sample of the amniotic fluid). ||
 * How is Cri-Du-Chat Diagnosed?! **
 * Cri-Du-Chat is usually identified at birth by the cat like cry. Other signs they look for is small head, mental retardation, and poor muscle tone.
 * How is Cri-Du-Chat Treated!?**
 * There really is no treatment for cri-du-chat. Children with this disorder go through therepy to improve motor skills, language skills, and to help them develop as normal as possible. ||
