Q97.1: Female with more than three X chromosomes

You have a congenital disorder, which means you were born with it. With this disorder, you have more than 3 X chromosomes.

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 chromosome and the Y chromosome determine a person’s biological gender. Men normally have one X chromosome and one Y chromosome. Women normally have 2 X chromosomes.

If you have more than 3 X chromosomes, you are female.

The condition can vary in severity. The more X chromosomes there are present, the more pronounced some of the characteristics and symptoms.

You can also have special features in your face, for example. This includes, for example, an extra fold of skin inside the corner of the eye. You may also have problems with speaking or learning. You may also have weaker muscle tone.

You may also have malformations of the bones, heart or ovaries. The heart is a muscle. The heart pumps blood through the body. The ovaries are part of the female genitals. There are two ovaries, one on each side. The ovaries sit low down in the abdomen. Egg cells mature in the ovaries. The egg cells can later develop into a child. The ovaries also produce various messenger substances.
