Some people think the words “genetic mutation” have a negative connotation, but in some cases, these anomalies can benefit people and have positive effects. From preventing damage and disease to adding a sixth sense, here are some rare but extraordinary examples of anomalies that work for you rather than against you!
1. Tetrachromacy
This genetic mutation gives people a superpower when it comes to seeing color. Individuals with tetrachromacy can see beyond the normal color spectrum because they have an extra cone cell in their eyes.
Most people only have three cones, but these folks have a fourth, allowing them to see a more impressive range of hues. This must lead to a jaw-dropping sensory experience on a daily basis, providing an appreciation for the everyday beauty in even the most mundane moments.
2. High bone density
If you’re one of these lucky few, your bones are significantly stronger than the average population, so congratulations! This anomaly changes the nature of bone tissue, making for a more resilient skeleton that can tolerate more damage than the average human. TThis means there is less chance of fractures and breaks.
They can feel free to play contact sports without fear and generally live more confidently. Beyond that, this anomaly offers scientists an opportunity to advance how we strengthen bones and treat osteoporosis or fractures for a more hopeful future.
3. Sickle cell trait
Those carrying the sickle cell trait are naturally resistant to malaria, which is one of the world’s worst diseases. They carry just a single copy of the anomaly that causes sickle cell disease, which causes abnormal hemoglobin production.
Although sickle cell disease can be devastating, those who only have the sickle cell trait experience milder symptoms with the added benefit of malaria protection. Not surprisingly, in populations where malaria is prevalent, more people have sickle cell trait. With specialists researching malaria resistance via this anomaly, we might just be able to get rid of malaria for good!
4. Lactase persistence
You may have heard of lactose intolerance. When people get older, they lose their ability to digest lactose (milk sugars) as well as they did when they were younger. But this mutation allows people to eat as many dairy products as they like without feeling the consequences!
Thanks to the alteration of the LCT gene, which controls the lactase enzyme, people with this genetic makeup get to reap all the benefits of dairy products, like increased calcium and vitamin D levels. It’s often seen in areas where high amounts of dairy products are consumed, showing you just how adaptive humans really are.
