What is (are) Cri du chat syndrome ?
Cri du chat syndrome, also known as 5p- (5p minus) syndrome or cat cry syndrome, is a genetic condition that is caused by the deletion of genetic material on the small arm (the p arm) of chromosome 5. Infants with this condition often have a high-pitched cry that sounds like that of a cat. The disorder is characterized by intellectual disability and delayed development, small head size, low birth weight, weak muscle tone in infancy, and distinctive facial features. While cri du chat syndrome is a genetic condition, most cases are not inherited.
