ICD-Code Q95.4: Individuals with marker heterochromatin
You have been found to have chromatin that is more tightly packaged than normal.
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.
Genetic information is very long. It is normally packaged to prevent it from taking up too much space in cells. Cells contains various proteins for this purpose. Some genetic information is wrapped around proteins, for example. The genetic information and the proteins together form chromatin. Chromatin in turn forms chromosomes.
Normally, certain parts of the genetic information are hardly needed or not needed at all. These segments are packaged tightly.
