Q99: Other chromosome abnormalities, not elsewhere classified

Q99.8: Other specified chromosome abnormalities

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.

You can have various symptoms depending on how the chromosomes are changed. Changes in the chromosomes can be hereditary, resulting in other family members sometimes being affected.
