The 4400: Genetic Healing

Genetic healing is a promicin-induced ability that allows its user to repair genetic defects, problems or disorders. The ability is activated by concentration, as its user can "feel" the damage to the chromosomes and command the broken genes to repair themselves. The ability is also, however, greatly limited, as it can only work on unborn children in utero, and the ability itself is a straight-swap; for every set of chromosomes healed, the user's mutate slightly, which, with time, causes insomnia, heart disease, spinal irregularities, and, ultimately, death within a year (if constantly used).
