  6. Common? • Cri-du-chat syndrome occurs in an estimated 1 in 20,000 to 50,000 newborns. Therefore it isn’t very common at all.

  7. Deadly? Shorten lifespan? • Although there is no cure, it is not deadly, and cannot shorten your lifespan.

  8. Can you be tested? When? How? • Testing can be done from a blood test which involves Karyotyping, where staining and examining chromosomes under a microscope is done. Cri du chat can also be detected before birth about 16-18 into pregnancy. The mother would have to undergo what is called amniocentesis. Amniocentesis is a procedure in which a needle is inserted into the abdomen and into the uterus to withdraw a sample of the amniotic fluid that surrounds the baby. The fluid or the cells that are in the fluid can be tested to

  10. Support groups • Health Share International is a support group that is online for people who can’t drive cars or get to a support group somewhere else. You can add friends who are just like you, and discuss your problems together.

  11. Interesting Facts! • The geneticist Jerome Lejeune identified cri-du-chat syndrome in 1963. • He also discovered the genetic abnormality that causes Down syndrome. • Cri-du-chat is one of the most common syndromes caused by a chromosomal deletion. • Between 1 in 20,000 and 1 in 50,000 babies. • In 80 percent of the cases, the chromosome carrying the deletion comes from the father's sperm rather than the mother's egg. • When deletions occur during the formation of an egg or sperm, it is caused by unequal recombination during meiosis. • When unequal recombination occurs at this location on chromosome 5, it causes cri-du-chat syndrome.
