Cri-du-chat Syndrome is caused by a deletion on the short arm of chromosome 5.

This deletion leads to a number of characteristic symptoms in infants, including microcephaly, developmental delay, cardiac abnormalities (commonly VSD), and a high-pitched mewing cry, giving rise to the name “cry of the cat” (cri-du-chat).
