FTSilver-3 Gene

The FTSilver-3 gene is a genetic structure present in 0.0000451% 0.0000000007% of humanity. It shows Hazardous properties.

Location
All humans carrying the FTSilver-3 gene are located in the city of █████████, █████.

Any attempts to leave by carriers or those pregnant with carrying infants are to be countered by the felling of trees across exits, strategic placement of lorries, or application of cloud-seeding particulates to snow clouds.

Attributes
Individuals bearing this gene are superficially identical to normal humans. However, dissection or MRI scanning will reveal the presence of a gland below the diaphragm, which is 3 degrees centigrade warmer than its surroundings and connected to the celiac trunk vessel.

If any attempt is made to damage the individual while they remain alive, the gland will begin to decrease in size and release a solution into the blood, saliva, and tissue fluid. This contains enzymes which, while they have no affect on the producer, react with other humans by digesting their skin and muscle.

The gene is dominant in type, and positioned on the 15th chromosome.
