Cri-du-chat Synodrome

By: Rebecca Villarreal

What is it?

The name of this syndrome is French for "cry of the cat". The cry is abnormal larynx development. The syndrome usually becomes less noticeable as the baby gets older, doctors have a harder time finding it after age 2. Cri-du-chat is caused by a deletion on the short arm of the chromosome 5.


signs are microcephaly, poor muscle tone and mental retardation.


There is no real treatment but children can go through a therapy to improve their motor skills, language skills, and to help them develop as normally as possible.


It is possible for children to inherit a broken chromosome from a parent who also has that disorder.
