Why do females get Cri du Chat?
The missing piece of the chromosome is the short (called ‘p’) arm of chromosome 5. Therefore cri du chat syndrome is said to be caused by deletion of chromosome 5p. Most cases are thought to occur as a result of damage to the chromosome during the development of the egg or sperm.
What does the 5th chromosome do?
People normally have two copies of this chromosome. Chromosome 5 spans about 181 million base pairs (the building blocks of DNA) and represents almost 6% of the total DNA in cells. Chromosome 5 is the 5th largest human chromosome, yet has one of the lowest gene densities….

What is 5p deletion syndrome?
Each year in the United States, approximately 50 to 60 children are born with 5p- Syndrome (five p minus), also known as Cat Cry Syndrome or Cri du Chat Syndrome. 5p- Syndrome is characterized at birth by a high pitched cry, low birth weight, poor muscle tone, microcephaly, and potential medical complications.
