Gene mutation protects heart

"A few lucky individuals have a gene that protects the heart from the effects of fatty food, research suggests. The discovery could lead to new treatments for heart disease, scientists believe. US investigators studied the DNA of more than 800 members of the Old Order Amish community, who are genetically similar and whose ancestry is easily traced. About 5% of the volunteers from Lancaster County, Pennsylvania, had a gene mutation that reduced levels of triglyceride fats in the blood and helped prevent heart disease. The gene, known as APOC3, produces a protein, apoC-III, that normally inhibits the breakdown of triglycerides. The fatty particles are associated with hardening and narrowing of the arteries." - Channel 4 News
