How was Edward's syndrome discovered?

For many syndromes, the syndrome actually takes place a lot before it is actually discovered. John Edwards is credited with discovering Edward’s Syndrome. He was a physician from Great Britain. In 1960, he began studying children in hospitals to determine what was wrong with them. He noticed many different commonalities and symptoms in these children.

Many of them had heart defects, retardation, growth disabilities, breathing problems and the intestines on the outside of the body. He also realized the cause which was when there was a third copy of the gene of the chromosome 18. It was a genetic disorder. It was also discovered by John Edwards that the patients usually died within the first year of birth. The result of this syndrome is fatal.
