Williams Syndrome Symptoms And Treatment

Williams Syndrome is a rare condition caused by missing genes on chromosome number 7. It was first identified by Dr. J. C. P Williams. It is not necessary that parents can have a family history of this condition, it can also occur in a person without any family history. But the parent has 50 percent chances of passing this condition to its offspring. It occurs in 1 in 8,000 births. Out of the 25 missing genes, one gene produces elastin which is a protein which allows the blood vessels and the other tissues in the body to stretch. Thus absence of one copy of the gene results in narrowing of the blood vessels.
