Q93: Monosomies and deletions from the autosomes, not elsewhere classified
Q93.3: Deletion of short arm of chromosome 4
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.
With this type of disorder, a piece of the 4th autosome has become detached and gone missing. So the genetic information is incomplete. If a piece of the 4th autosome is missing it may indicate Wolf-Hirschhorn Syndrome.
Wolf-Hirschhorn Syndrome can take different forms. For example, it may involve various visible facial characteristics, such as the eyes being further apart. Those affected are usually smaller than their peers. Physical and mental abilities may be limited. Seizures may occur. Certain organs can be deformed, too.
