Q92.3: Minor partial trisomy
Part of a chromosome is present three times.
Somatic cells usually hold a complete blueprint of your body. This blueprint consists of genetic information. The genetic information is encrypted in the chromosomes. In humans, somatic cells usually have 23 pairs of chromosome, so 46 chromosomes in all. Apart from the male sex chromosomes, each chromosome is normally present twice per cell.
The chromosomes are passed on to the child by both parents. To this end, the chromosomes are in the mother’s egg cell and the father’s sperm cell. When the egg cell and the sperm cell merge, a new cell forms. Then, from this cell, the cells for a new body form.
Part of a chromosome may be present three times instead of twice. This usually happens when the chromosomes in the egg or sperm cell have already been changed. The effects depend on which part of which chromosome is present three times.

- V: Tentative diagnosis
