Down syndrome is characterized by an extra copy of chromosome 21, Turner syndrome involves a missing or incomplete X chromosome in females, and Klinefelter syndrome is caused by an extra X chromosome in males.
What are examples of genetic disorders that is caused by insertion of extra codons in the x sex chromosome?
The phenomenon of having an extra chromsome is called anueploidy. Depending on the chromosome of which the extra copy exists, there are many disorders.Down Snydrome is the most common disorder associated with an extra autosomal chromosome, but it is not the only one. The other condintions that come from extra copies of an autosome (non-sex chromosome) that result in the most live births are:Edward's Syndrome from an extra copy of 18 andPatau syndrome which is caused by an extra 13.As for sex chromosomes,an extra X chromosome results in Klinefelter's syndrome (XXY) in males andmetafemale or XXX syndrome in women.Males with an extra Y are simply refered to as having XYY syndrome.
Which genetic disorder does an extra chromosome cause?
An extra chromosome can cause genetic disorders such as Down syndrome, which is caused by an extra copy of chromosome 21. This leads to developmental delays, intellectual disabilities, and certain physical characteristics.
What does it mean when someone has an extra chromosome?
If someone has an extra chromosome it means there was a genetic mutation that is abnormal in human development. It may result in problems with the person affecting them on a basic level, or may go fully unnoticed. A common disorder that can be caused by having an extra chromosome is Down's Syndrome.
What can an extra chromosome do?
Having an extra chromosome, known as trisomy, can lead to genetic disorders such as Down syndrome (trisomy 21) or Edwards syndrome (trisomy 18). These disorders can affect physical and intellectual development, leading to characteristic features and health challenges. The specific impact of an extra chromosome varies depending on which chromosome is affected.
What is the difference between Edward's syndrome and Patau's syndrome?
