Q93: Monosomies and deletions from the autosomes, not elsewhere classified

Q93.2: Chromosome replaced with ring or dicentric

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.

With this change, pieces of one or more autosomes are broken off. So the autosomes concerned have a changed shape. The broken pieces might go missing. In this case the genetic information is incomplete. When the genetic information is incomplete, it can cause problems.
