A genetic disorder caused by a deletion of a part of the short arm (p) of chromosome 5, and characterized by the cat-like cry symptom in affected infants


In 1963, Jerome Lejeune and his team was first to report regarding infants making a cat-like cry (likened to the meowing of a Parisian cat). Hence, the name: cri du chat -- which is a French term, meaning cat-cry.

Children with cri du chat syndrome show significant delay in mental development, low birth weight, and physical malformations (e.g. microcephaly, hypertelorism, micrognathia, wide eyes, and skin tags near the eye).

Cri du chat syndrome is a genetic disorder caused by a deletion of a part of a chromosome (5p).
