15 Extemely Rare Genetic Features That You Probably Don’t Have

Everyone has a unique combination of genetic features that differentiate them from the rest of the population, guaranteeing that no two people are exactly alike. Many have rare mutations that give them abilities or physical features that most people don’t share. Genetic mutations are a vital part of evolution, and they can lead to differences that provide advantages as well as disadvantages.

Mutations in humans are extremely rare, and you probably don’t have one, but those who do may have super strength, unbreakable bones, or striking physical features. Genetic abnormalities can lead to exceptional physical qualities that make those who have them particularly unique. Distinctive makeups in DNA give people unusual conditions that can be beneficial but may also cause complications.

Some People’s Bones Just Don’t Break

In 1994, scientists discovered a genetic mutation known as LRP5. The gene regulates the production and release of a protein that plays a major role in bone density. The mutation was discovered when a man involved in a serious car crash didn’t suffer any fractures or broken bones. Researchers later found that he had family members who also had incredibly strong skeletons, one of whom underwent several failed hip replacements because doctors were unable to screw the prosthesis into his bone.

Tests showed that the group had bones nearly eight times denser than the average person’s, making them so tough that they were almost impossible to break under normal circumstances.

This Mutation Creates Very Strong Children

 

Although it’s been well documented in mice and cattle, there have only been a few instances of inactive myostatin genes in humans. The condition causes people to develop incredibly strong muscles. Children who are born with the mutation have lean and well-defined muscles at a young age, possessing greater strength than children of similar ages.

Long-term health issues associated with the disorder are unknown, as it hasn’t been widely researched.

There Are People Who Can’t Contract HIV

 

Up to 1% of those of Northern European descent may be resistant to HIV because of an incredibly rare genetic mutation called CCR5 delta 32. This abnormality essentially causes the CCR5 co-receptor to be much smaller than it normally is, so the HIV virus cannot enter cells.

The receptor is closed, preventing the virus from taking hold in victims’ bodies. Scientists have been working on a cure for the disease that involves using stem cells to mimic the genetics of those immune to HIV.
