What is Cri du Chat syndrome?
Cri du chat syndrome - also known as 5p- syndrome and cat cry syndrome - is a rare genetic condition that is caused by the deletion (a missing piece) of genetic material on the small arm (the p arm) of chromosome 5. The cause of this rare chromosomal deletion is unknown.
How is Cri du Chat treated?
Treatment for cri du chat syndrome
physiotherapy to improve poor muscle tone.
speech therapy.
communication alternatives, such as sign language, since speech is usually delayed, often severely.
occupational therapy to teach coping strategies and new skills.
How is a child identified as having Cri du Chat?
There are a number of features of cri du chat syndrome, which include: The baby has a cry which is high-pitched and has been described as sounding like a cat. The mewing cry becomes less obvious with increasing age. Sucking and feeding problems are common in the first year of life.
Is Cri du Chat inherited?
Most cases of cri du chat syndrome are not inherited. The chromosomal deletion usually occurs as a random event during the formation of reproductive cells (eggs or sperm) or in early fetal development.
Can Cri du Chat be prevented?
There is no known way to prevent cri-du-chat syndrome. Even if you don't display symptoms, you may be a carrier if you have a family history of the syndrome. If you do, you should consider getting a genetic test.
Who gets Cri du Chat?
Cri-du-chat syndrome occurs in an estimated 1 in 20,000 to 50,000 newborns. This condition is found in people of all ethnic backgrounds
What does the 5th chromosome do?
Because researchers use different approaches to predict the number of genes on each chromosome, the estimated number of genes varies. Chromosome 5 likely contains about 900 genes that provide instructions for making proteins. These proteins perform a variety of different roles in the body
Are there any prenatal tests for Cri du Chat?
Cri du chat syndrome can be detected before birth if the mother undergoes amniocentesis testing or chorionic villus sampling (CVS).
Is Cri du Chat more common in a certain race?
The condition tends to affect females more often than males and is diagnosed in people of all ethnic backgrounds. While Cri du Chat is related to genes, it's not necessarily an inherited condition. Most cases occur de novo (or spontaneously) during embryonic development.

What type of abnormality causes Cri du Chat?
Cri du chat syndrome is a chromosomal disorder caused by a partial deletion (monosomy) of a varying length of the short arm (p) of chromosome 5. Chromosomes, which are present in the nucleus of human cells, carry the genetic information for each individual.
Is Cri du Chat syndrome autosomal?
Cri-du-chat syndrome is an autosomal deletion syndrome caused by a partial deletion of the p arm of chromosome 5 (5p) and is characterized by a distinctive, high-pitched, catlike cry in infancy with growth failure, microcephaly, facial abnormalities, and mental retardation throughout life. See the images below.
How was Cri du Chat syndrome discovered?
Cri Du Chat Syndrome Home
Cri du Chat Syndrome ("Cry of the cat" in French) is a genetic disorder caused by the loss or misplacement of genetic material from the fifth chromosome. It was first identified in 1963 by Professor Lejeune, who also identified the genetic cause of Down Syndrome.
What is Lejeune syndrome?
Lejeune syndrome - a disorder characterized by microcephaly, antimongoloid palpebral fissures, epicanthal folds, micrognathia, strabismus, mental and physical retardation, and a characteristic high-pitched catlike whine. Synonym(s): cri-du-chat syndrome.
What is cat cry?
Cri-du-chat (cat's cry) syndrome, also known as 5p- (5p minus) syndrome, is a chromosomal condition that results when a piece of chromosome 5 is missing . Infants with this condition often have a high-pitched cry that sounds like that of a cat.
The clinical symptoms of cri du chat syndrome usually include a high-pitched cat-like cry, mental retardation, delayed development, distinctive facial features, small head size (microcephaly), widely-spaced eyes (hypertelorism), low birth weight and weak muscle tone (hypotonia) in infancy.
What does Cat Cry Syndrome sound like?
A high-pitched, mewling cry that sounds like a cat. Low muscle tone.
