Is cri du chat syndrome?
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.
Is Cri du Chat curable?
Most fatal complications occur before the child’s first birthday. Children with cri-du-chat who reach age 1 generally will have a normal life expectancy. But the child will most likely have lifelong physical or developmental complications.
Why do females get Cri du Chat?
Therefore cri du chat syndrome is said to be caused by deletion of chromosome 5p. Most cases are thought to occur as a result of damage to the chromosome during the development of the egg or sperm.
What is the life expectancy of someone with Cri du Chat?
The survival for children with cri du chat is generally good. Most syndrome related deaths occur within the first year of life. Several children have lived to be over 50 years of age. Genetic counseling is recommended for affected individuals and their families.
Can Cat Cry Syndrome be detected before birth?
Cri du chat syndrome can be detected before birth if the mother undergoes amniocentesis testing or chorionic villus sampling (CVS). This testing would only be recommended if the mother or father is known to have a chromosome rearrangement, or if they already have a child with cri du chat syndrome.
Are people with Cri du Chat fertile?
No specific treatment is available for cri-du-chat syndrome. Genetic counseling is indicated. Female patients are fertile and can deliver viable affected offspring, with an estimated recurrence risk of 50%. Recurrence risk for a de novo case is 1% or less.
Is Cri du Chat monosomy?
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.
What are the characteristics of Cri-du-chat syndrome?
Cri-du-chat syndrome is characterized by intellectual disability and delayed development, small head size (microcephaly), low birth weight, and weak muscle tone (hypotonia) in infancy. Affected individuals also have distinctive facial features, including widely set eyes (hypertelorism), low-set ears, a small jaw, and a rounded face.

What is the history of Cri du Chat?
Most cases are thought arise from spontaneous (de novo) genetic errors very early in embryonic development. The disorder was first described in the medical literature in 1963 by doctor Lejeune who named the disorder after the distinctive cat-like cry. In French, Cri du chat translates into “cry of the cat”.
