Loss of a gene has been linked to an increased risk of heart disease


For years, scientists have been researching why humans are at increased risk for heart disease. In the end, it turns out, this is because a gene that existed in the human race two and a half million years ago no longer exists in humans today.

The researchers monitored the mutation in life-sustaining genes (CMAH) by implanting them in mutated mice.

(CMAH is a gene that produces a sugar molecule called glycolinuramine acid that causes chronic inflammation in modern humans.)
