The condition is usually diagnosed at birth, based on physical abnormalities and other signs like the typical cry.

Does Cri du Chat affect the brain?

A developmental field may connect the brain and the affected clivus region of the cranial base with the laryngeal region from which the characteristic cry derives.

What kind of mutation is ‘Cri du chat’ syndrome?

Patients with Cri du Chat Syndrome have a deletion of a segment of chromosome 5. In 85-90% of cases, this genetic disorder is caused by a random mutation, also known as a “de novo” mutation (new mutation).
