F84.2: Rett syndrome

You have Rett syndrome.

When beginning its development, every single cell in the body contains a complete blueprint of the body. This blueprint consists of genetic information. The genetic information is encrypted in the chromosomes. Every human cell normally contains 23 chromosome pairs, i.e. a total of 46 chromosomes. The X and Y chromosomes determine the different biological sexes. Normally, women have two X chromosomes and men have one X chromosome and one Y chromosome.

Rett syndrome usually involves a change to the genetic information on an X chromosome. Rett syndrome is congenital, which means you were born with it.

With this disorder, you initially develop normally both before birth and for a short while afterwards. You then become unable to do things that you used to be able to do. You may be unable to speak properly. You may find it hard to deal with other people. You may make repeated hand movements as though you are washing your hands. You can find it difficult to coordinate your movements. Walking and standing may be unstable. Your head may grow more slowly than is usual. Your intellectual capabilities may also gradually decline.

Rett syndrome can come in different forms. It may also involve other difficulties.
