What is Williams Syndrome?
Williams syndrome is a genetic disorder which leads to developmental delays. Williams Syndrome develops due to deletion of a part of chromosome 7. The quantity of deletion leads to the number of symptoms. More deletion means severe symptoms and vice versa. The deletion occurs as a chance. Children with Williams Syndrome may have learning problems along with heart and blood vessel problems. At the same time, these children are usually good with verbal skills,friendly, social, and enjoy music.
