==Williams syndrome is a rare genetic disorder. This disorder affects a child's growth,cognitive development, and physical appearance. This condition is caused by missing genes, to be specific, elastin. Elastin is a protien in connective tissue that is elastic and allows many tissues in the body to resume their shape after stretching or contracting. Elastin helps skin to return to its original position when it is poked or pinched. Elastin is also an important load-bearing tissue in the bodies of mammals and used in places where mechanical energy is required to be stored. Since people with Williams syndrome have lack of elastin protein, they have circulatory system disorders and heart defects.Parents dont have to have Williams syndrome to give it to their children. If a child with williams syndrome has a child, theirs a 50% chance that the child will have Williams syndrome.==
