What is Williams Syndrome?
How does someone get Williams Syndrome?
When there is a deletion mutation on chromosome 7 during fermentation, Williams Syndrome is given to the baby. However, it is very rare and occurs only in every 1 out of 10,000 babies. Williams Syndrome is equally possible in all gender and ethnicity groups. Usually it is not inherited from a parent, like other genetic disorders.
How do I know when someone has Williams Syndrome?
If you are not sure if your child or someone you know has it, you can also get them tested for Williams Syndrome. Using a method called FISH (fluorescent in situ hybridization), DNA sequences are labeled and held under a UV light. If the genes light up, the patient does not have Williams Syndrome.
