During the formation of the sperm or the egg cells in our bodies, a part of chromosome 5 gets deleted. If this specific gamete goes through fertilization, the offspring will be affected with the “cri-du-chat” syndrome. It is not an inheritable disorder because the event of partial chromosome deletion occurs in a complete random manner. Therefore, anyone can get this genetic disorder because of the deletion of chromosomes in their DNA. It is most likely to occur in females more than males (3:2 ratio), but follows no specific ethnicity.
