What are some diseases traits or disorders associated with chromosome 5?
Cri du Chat syndrome Cri du chat (‘cat cry’) syndrome is also known as 5p-syndrome is caused by a deletion on the short arm of chromosome 5 (5p). The most common symptoms are a ‘cat-like cry’, a high-pitched voice, severe early intellectual disability, low-set backwardly rotated ears and prominent eye-folds.
Which genetic disease is caused by a deletion on chromosome 5?
Cri du chat syndrome (CdCS or 5p-) is a rare genetic disorder in which a variable portion of the short arm of chromosome 5 is missing or deleted (monosomic).
What disease is a Monosomy?
Turner syndrome is a genetic condition caused by an abnormality on one of your sex chromosomes. It’s also called monosomy X, gonadal dysgenesis, and Bonnevie-Ullrich syndrome. Only the female sex develops this condition. Turner syndrome occurs when part or all of one of your X chromosomes is missing.
How is Cri du Chat caused?
Cri du chat syndrome is a rare genetic disorder caused by a missing section on a particular chromosome known as Chromosome 5. Sometimes, material from another chromosome is missing as well. Around one in every 50,000 or so babies is diagnosed with this disorder.
What are 5 chromosome traits?
Some of the genes present on chromosome 5 include:
- ADAMTS2 that codes for metallopeptidase with thrombospondin motifs-2.
- APC that stands for adenomatosis polyposis coli or colonic polyps.
- EGR1 that codes for early growth response protein 1.
- DTDST that codes for diastrophic dysplasia sulfate transporter.
What does chromosome 5 determine?
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 happens if you are missing chromosome 5?
Cri-du-chat (cat’s cry) syndrome, also known as 5p- (5p minus) syndrome, is a chromosomal condition that results when a piece of chromosome 5 is missing . Infants with this condition often have a high-pitched cry that sounds like that of a cat.
Is monosomy worse than trisomy?
In general, a monosomic for a particular chromosome is more severely abnormal than is the corresponding trisomic.
What is the most common monosomy?
Human monosomy Turner syndrome is the only full monosomy that is seen in humans — all other cases of full monosomy are lethal and the individual will not survive development.
What is the survival rate of Cri du Chat?
With contemporary interventions, the chance of survival to adulthood is possible. Currently, the mortality rate of cri-du-chat syndrome is 6-8% in the overall population. Pneumonia, aspiration pneumonia, congenital heart defects, and respiratory distress syndrome are the most common causes of death.
What is the 5th chromosome responsible for?
Because chromosome 5 is responsible for many forms of growth and development (cell divisions) changes may cause cancers….

What are the 5 chromosomal abnormalities?
Examples of chromosomal abnormalities include Down syndrome, Trisomy 18, Trisomy 13, Klinefelter syndrome, XYY syndrome, Turner syndrome and triple X syndrome.
What are the different types of monosomy disorders?
Cri du chat syndrome is a monosomy disorder related to a missing part of chromosome 5. Monosomy disorders occur during fetus development and are characterized by a partial or full missing pair of a chromosome. While these disorders are relatively rare, the most common are Turner syndrome and Cri du chat syndrome.
What causes an extra chromosome on chromosome 5?
Causes. If any other chromosome is involved with chromosome 5 in an unbalanced translocation, the individual will have extra and missing material. Depending on which chromosomes are inherited, a duplication of 5p may be present with missing chromosomal material from the other chromosome involved in the translocation.
How is Cri du chat syndrome a monosomy disorder?
Cri du chat syndrome is a monosomy disorder related to a missing part of chromosome 5. Monosomy disorders occur during fetal development. Along with learning and physical disabilities, monosomy disorder causes the larynx to develop abnormally.
Are there any physical symptoms associated with trisomy 5p?
Some affected individuals may have heart defects and seizures. Not all individuals with trisomy 5p will have all of the symptoms of the disorder. The symptoms and physical findings associated with trisomy 5p are variable and depend on the location and size of the duplicated segment.
