Cri-Du-Chat Syndrome

Cri-Du-Chat Syndrome is a congenital disease characterized by delayed mental and physical development, as well as a specific cry of infants, reminiscent of a cat's meow.

The cause of the syndrome is the deletion (loss) of part of the genetic material on the short arm of the 5th chromosome. This leads to disruption of the development of the brain and other organs.

Main symptoms:

  1. Mental retardation (ranges from mild to severe)

  2. Muscular hypotonia

  3. Heart defects

  4. Facial skeleton defects

  5. Microcephaly

  6. Characteristic high-pitched squeaky cry in infancy

  7. Difficulties with speech and communication

  8. Slow growth

Diagnosis is based on karyotype analysis and detection of 5p deletion. Treatment of Cry Cat syndrome is symptomatic and is aimed at correcting developmental disorders. The prognosis largely depends on the degree of mental retardation.



Cri du chat syndrome is a rare genetic disorder that causes congenital mental retardation and multiple physical abnormalities. It is characterized by a high-pitched baby cry, reminiscent of a cat's meow.

Cri-cat syndrome develops as a result of a chromosome disorder when one arm of chromosome 5 is missing. This leads to impaired brain development and other physical abnormalities.

The disease can present with a variety of symptoms, including mental retardation, speech problems, hearing loss, learning difficulties, short stature, and abnormalities of the face, limbs and heart.

Treatment for cry-the-cat syndrome includes medication and surgery. However, despite all efforts, many children with this disease have limited abilities and require constant medical supervision and assistance.

It is important to note that Cri Cat Syndrome is a rare genetic disorder, but its symptoms can be quite severe. Therefore, it is important to know about it and be prepared for possible problems associated with this disease.



Cri-du-chat syndrome is a genetic disorder that causes mental retardation and multiple physical abnormalities. It occurs as a result of the absence of one arm of chromosome 5 in the set of chromosomes.

In Cri de Cat syndrome, babies begin to cry immediately after birth, which sounds like a cat crying. This cry may continue for several hours or days until the baby begins to calm down and sleep. Children with Cri Cat Syndrome may also have other physical abnormalities, such as short stature, facial abnormalities, and problems with speech and hearing development.

The disease develops because the missing arm of chromosome 5 is an important regulator of brain and nervous system development. This can lead to mental retardation in children who suffer from Cri Cat Syndrome.

Treatment for cry-the-cat syndrome includes the use of medications that can help improve brain and nervous system development, as well as help with the child's learning and development. Exercise and a special diet may also be recommended to support the child's health and development.

Overall, Cri Cat Syndrome is a serious genetic disorder that requires medical intervention and family and community support. It is important to understand that this condition is not incurable, and with proper treatment and care, children with Cri Cat Syndrome can lead normal lives and achieve success in school and work.
