What are the symptoms of 5p minus syndrome?
What are the symptoms of 5p minus 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.
What happens if you are missing chromosome 5?
A deletion in the short arm of chromosome 5 is an example of an unbalanced translocation, which is a chromosomal rearrangement with extra or missing genetic material. Unbalanced translocations can cause birth defects and other health problems such as those seen in cri-du-chat syndrome.
What is the life expectancy for people with Cri du Chat Syndrome?
The survival for children with cri du chat is generally good. Most syndrome related deaths occur within the first year of life. Several children have lived to be over 50 years of age. Genetic counseling is recommended for affected individuals and their families.
What does chromosome 5 represent?
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 the function of chromosome 5?
Because researchers use different approaches to predict the number of genes on each chromosome, the estimated number of genes varies. Chromosome 5 likely contains about 900 genes that provide instructions for making proteins. These proteins perform a variety of different roles in the body.
Can chromosome deletions be fixed?
“When chromosome duplication compensates for the loss of the corresponding ring chromosome with a deletion, this provides a possible avenue to correct large-scale problems in a chromosome that have no chance of being corrected by any other means.”
What are the signs and symptoms of chromosome 5p deletion?
Features that often occur in people with chromosome 5p deletion include developmental delay, intellectual disability, behavioral problems and distinctive facial features. [1] [2] Chromosome testing of both parents can provide more information on whether or not the deletion was inherited. In most cases, parents do not have any chromosomal anomaly.
What are the signs and symptoms of 5p syndrome?
Here’s some things to look for when it comes to development with 5P- syndrome. Gross and fine motor skills. Expressive speech and language delays. Communicate by sign language, communication devices, gestures and a few basic words. Poor muscle tone (hypotonia) Slow growth associated with failure to thrive.
Is it okay to cry after being diagnosed with 5p-Deletion?
It’s okay to cry; it’s okay to grieve; it’s okay to vent. After the diagnosis the parent will most likely see a genetic counselor. Depending on the counselor’s experience, he/she may or may not give accurate information. 5p- deletion is a spectrum disorder. Individuals with this syndrome will range from mild to severe in developmental delays.
How do I contact Gard for chromosome 5p deletion?
Please reach out to a GARD Information Specialist at 301-251-4925. Chromosome 5p deletion is a chromosome abnormality that occurs when there is a missing ( deleted) copy of genetic material on the short arm (p) of chromosome 5.
