Researchers Looking For Genes That Prevent Diseases.

In recent years, a few astounding protective gene mutations have been discovered, pretty much by accident. One prevents H.I.V. from entering cells and another enormously reduces the amount of LDL cholesterol, the dangerous kind, that people make. Both led to drugs. The AIDS drug is a mainstay of treatment, and the cholesterol drug is in the final stages of testing. Researchers, using systematic searches of genetic databases, also found alterations in some genes that partially protect from diseases like heart disease, osteoporosis, Type 2 diabetes and Alzheimer’s. But now some are starting a more ambitious project — a search for mutations that provide complete protection. http://www.nytimes.com/2014/12/29/health/in-a-new-approach-to-fighting-disease-helpful-genetic-mutations-are-sought.html?ref=health&_r=0
