What Is Turner Syndrome?
2. Causes
As mentioned, Turner syndrome is a type of chromosome disorder and, in this instance, it is the X and Y chromosomes that are affected. In ‘healthy’ people, girls will inherit one X chromosome from each of their parents. In patients that have Turner syndrome, there is an issue with one of these chromosomes.
There are different types of problem with the chromosomes that can cause Turner syndrome. One of these is mosacism, which means that some of the cells will have two complete X chromosomes, but others will have only one. Monosomy means that all cells have only one copy. Other problems include having only part of an x chromosome in the faulty copy, while other patients can have part of a Y chromosome in what should be an X chromosome.
