Useful Mutations :

 Useful human mutations include:

• The CCR5-delta 32 mutation that makes carriers immune to HIV.
• The LCT MCM6 single nucleotide polymorphism that lets people digest milk throughout their whole lives.
• The Apo-AIM mutation that makes a group of carriers in Italy almost immune to arteriosclerosis, and lowers incidence of heart attack and stroke.
• The LRP5 mutation that makes carriers immune to osteoporosis.
• The ACTN3 mutation that makes its carriers exceptionally fast and strong (it was discovered by doing gene studies of elite athletes).
• The hDEC2 mutation that allows its carriers to function normally on only 4 hours of sleep a night (Thomas Edison is believed to have had this mutation).
• The EGLN1 and EPAS1 mutations that allow people to thrive at high altitudes without experiencing altitude sickness.
• The leukocyte antigen-B14 mutation that makes carriers highly resistant to Ebola.
• The PDE10A mutation that allows people to hold their breath for a very long time, common among the free-diving Bajau people.

That’s not an exhaustive list. There are beneficial mutations that confer tetrachromatic color vision, high-fidelity tasting, and all kinds of other cool stuff.
