Q91: Edwards syndrome and Patau syndrome
Q91.4: Trisomy 13, meiotic nondisjunction
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.
Trisomy 13 is a congenital disorder, where you have one chromosome more than normal. Instead of 2 copies of chromosome 13, you have 3 copies of chromosome 13. This disorder is therefore called Trisomy 13. In some cases, only a part of chromosome 13 is present three times.
Trisomy 13 is a very serious condition. Trisomy 13 can vary greatly in severity. Certain visible features are apparent, for example, on the face and hands. The head is smaller than normal. You can also have diseases affecting the heart and kidneys. Seizures may occur. You can have severe intellectual disability. Trisomy 13 can also cause you to have many other symptoms.
