Laron Dwarfism
Medical Mystery
It is an extremely rare genetic condition called Laron Dwarfism -- but it may help researchers unlock a cure for cancer and other deadly diseases. ABC News correspondent Jeffrey Kofman travels deep into southern Ecuador, where one-third of the world's 300 people with the disorder live. They do not grow taller than four feet, but researchers who study Laron dwarfism say they have not found a single case of cancer or diabetes among these people.
