Super gene

A super gene is a region of a super's DNA which determines their power. It is hereditary, which means that powers can be passed down through the generations. Super genes somehow "turn off" when the super turns eighteen years old, and they lose their power. The cause of this is unknown.

Currently, only two super genes have been discovered: the telepathy (mind-reading) gene, possessed by Stacy Johnson, and the teleportation gene, possessed by Reagan Matthews and formerly her mother.

In Reagan, We Have to Talk
The cause of Reagan Matthews' newfound power of teleportation is not scientifically explained in Reagan, We Have to Talk. However, Reagan's mother explains that she also had the ability to teleport until she was eighteen years old.

In Second Thoughts
In Second Thoughts, Stacy Johnson discovers that she has the power to read minds. When Dr. Shrutika (her therapist) realizes what's going on, she alerts a team of doctors who then analyze Stacy's DNA to find the cause of her powers. Dr. Silverstein is the first person to discover the super gene. The doctors plan to sell the super gene on the black market.

In Reagan & Stacy
Knowledge of the super gene seems to have become widespread among medical staff and the politically elite by the time of Reagan & Stacy. President Hillary Clinton mentions that they "already have the mind reading gene," which means her administration somehow acquired it from the doctors in Second Thoughts. Under orders of President Hillary, a group of doctors kidnap Stacy Johnson thinking that she possesses the power of teleportation instead of mind reading. Hillary and her minions end up dead instead of acquiring the teleportation gene.
