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.
DEADLY? SHORTEN LIFESPAN? Although there is no cure, it is not
deadly, and cannot shorten your lifespan.
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
TREATMENT? CURE OR TREAT SYMPTOMS? Treatment includes supportive care and
development therapy

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.
