Origins of the syndrome ?We are all made of cells. At the center of the cells, there is a kernel, which contains long filaments of DNA. The DNA codes our hereditary inheritance, which means our morphological specificities… There are 46 long filaments of DNA that corresponds to our chromosomes. All the chromosomes go by two, each of them have numbers that go with their functions and aspects (2 chromosomes number 1…)
In the Williams’ syndrome, a little bit of DNA is lacking on one of the two chromosomes 7. This lacking part contains several important genes like “Elastine” that is useful for the walls of the vessels like the aorta. The lost of one copy (one of the two chromosomes) of this gene is responsible for the cardiac problems of the children that have the syndrome. The other symptoms of the disease are probably due to a loss of other genes next to the “elastine” gene.
