The Cri du Chat syndrome (CdCS) is a genetic disease resulting from a deletion of variable size occurring on the short arm of chromosome 5 (5p-). The incidence ranges from 1:15,000 to 1:50,000 live-born infants. Cri du chat syndrome (CdCS or 5p-) is a rare genetic disorder in which a variable portion of the short arm of chromosome 5 is missing or deleted (monosomic). Cri-du-chat is one of the most common syndromes caused by a chromosomal deletion.

Among the cases described in this study, three patients have lived to be over 50 years of age.

The fact that the phenotype is well recognisable, in spite of the variability in deletion size, has led to the hypothesis that a critical region causes the characteristic clinical picture when present in a hemizygous situation: Niebuhr located this region in a narrow area around 5p15. The first three mosaic cri du chat syndrome patients with two rearranged cell lines. The following colleagues collaborated in providing patients, material and clinical information: G.

These may include a small head (microcephaly) and high forehead; highly arched eyebrows; widely spaced eyes (ocular hypertelorism); vertical skin folds that cover the eyes’ inner corners (epicanthal folds); a “beaked” nose with an abnormally wide nasal bridge; a downturned mouth; an unusually short vertical groove in the middle of the upper lip (philtrum); and/or large, malformed ears. This suggests that today's CdCS patients have a better outcome than those in the past.
