Q93.0: Whole chromosome monosomy, meiotic nondisjunction
The number of chromosomes has changed.
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. There are two different types of chromosomes. They are autosomes and sex chromosomes. There are 22 pairs of autosomes per somatic cell, and the 2 remaining chromosomes are the sex chromosomes.
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.
With this disorder, individual autosomes or all 22 are only present once per cell rather than twice. This is because there were fewer autosomes than usual in the egg cell or the sperm cell. The disorder can have serious health consequences.
Additional indicator
On medical documents, the ICD code is often appended by letters that indicate the diagnostic certainty or the affected side of the body.
- G: Confirmed diagnosis
- V: Tentative diagnosis
- Z: Condition after
- A: Excluded diagnosis
- L: Left
- R: Right
- B: Both sides
