ICD-Code Q98.9: Sex chromosome abnormality, male phenotype, unspecified
You have a congenital disorder, which means you were born with it. This disorder causes you to have an unusual number or unusual structure of sex chromosomes.
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.
The X chromosome and the Y chromosome determine a person’s biological gender. Men normally have one X chromosome and one Y chromosome. Women normally have 2 X chromosomes.
