The syndrome gets its name from dd characteristic cry of affected infants, which is similar to that of a meowing kitten, due to problems with the larynx and nervous system.

Furthermore, two patients who showed an interstitial deletion and a terminal deletion that did not include the critical region and did not show CdCS clinical features, confirmed that not all 5p deletions result in the CdCS phenotype [ 566970 ]. In addition, he had a eindrome, cat-like cry, characteristic of cri-du-chat syndrome. Please review our privacy policy.
