21.   Gelsinger suffered from an inherited liver condition caused by a genetic flaw.

22.   Gelsinger was enrolled in an experiment designed to test whether new genes could correct an inherited liver condition caused by a genetic flaw.

23.   Generally it takes several different genetic flaws, accumulated over a lifetime, to finally tip a cell into uncontrolled growth.

24.   In gene therapy, a working gene is inserted to compensate for genetic flaws like those that lead to muscular dystrophy, a progressive muscle disease that causes weakness.

25.   In gene therapy, working genes are inserted to compensate for genetic flaws, such as the ones that lead to OTC.

26.   It is much more aggressive than breast cancer fueled by other genetic flaws.

27.   Now, with this latest breakthrough, they will be able to create specific genetic flaws in the lab and then try to find drugs that work.

28.   Sadelain earlier achieved a similar success in mice by correcting the genetic flaw that causes thalassemia, a blood disorder related to sickle cell anemia.

29.   Scientists have discovered another genetic flaw that seems to raise the risk of obesity.

30.   Scientists in recent years have found the genetic flaws that cause both conditions.
