Aarskog syndrome is a disease that affects a person's height, muscles, skeleton, genitals, and appearance. It is passed down through families (inherited).
Aarskog syndrome is a genetic disorder that is linked to the X chromosome. It affects mainly males, but females may have a milder form. The condition is caused by changes (mutations) in a gene called "faciogenital dysplasia" (FGD1).
Symptoms of this condition include:
Exams and Tests
These tests may be done:
Moving the teeth may be done to treat some of the abnormal facial features a person with Aarskog syndrome may have.

When to Contact a Medical Professional
Call your health care provider if your child has delayed growth or if you notice any symptoms of Aarskog syndrome. Seek genetic counseling if you have a family history of Aarskog syndrome. Contact a genetic specialist if your provider thinks you or your child may have Aarskog syndrome.
Genetic testing may be available for people with a family history of the condition or a known mutation of the gene that causes it.
