Cri du chat syndrome

Cri du chat is a rare disorder due to a partial deletion on chromosome 5. Its name is a French term referring to the characteristic cat-like cry of affected children. It was first described by Jérôme Lejeune in 1963. The condition affects an estimated 1 in 22,000 live births across all ethnicities and is more common in females by a 4:3 ratio.
