There's a DNA mutation that makes you immune to the plague and HIV!

People can be infected with many different bacteria and viruses, but some people get sicker from these bugs than others. Do our genes cause some of that difference?

The answer is yes, different versions of important genes change how easy it is for a person to be infected. The study of these genes might lead to new drugs to block or slow down an infection.

There are people that are naturally immune to many diseases, for example, people that lack a protein called CCR5, a protein that is needed to open a door in our cells that allows the HIV go in, are naturally immune to it.

People inherit this gene from both parents and it can only be found in 1 % of Caucasians.
