Ambras Syndrome

• Percentage Of People Who Have It: Less Than 1%

Ambras Syndrome is often referred to as the “werewolf disease.” The more scientific name for this is hypertrichosis, however. Those who have it will be completely covered in hair all over their bodies, regardless of gender/sex. For some, it might be isolated to certain areas of the body but most will be covered entirely. Those who have Ambras will not just be covered in a little hair. Rather, it is usually long, thick hair that can make one resemble our ancestors, the great ape. It rose to notoriety during the Middle Ages, mostly in Europe. Only 50 people were said to have had it since then.

However, a relatively large family was eventually uncovered that had been living away from civilization for decades in an attempt to avoid issues with the public. It is now estimated several more could exist but might be hiding out. The gene responsible for this condition is called “TRPS1.” This gene causes a disruption in messages sent to cells regarding the development of follicles, which then results in the excessive hair growth Ambras Syndrome causes. Treatment now exists for people affected. This is almost always genetic, but there are some medical conditions or medicines that cause it too.

Superhuman Taste Buds

• Percentage Of People Who Have It: Roughly 25%

Rare genetic traits like superhuman taste buds might seem odd. However, those with this ability are able to accurately taste pretty much anything added to what they consume. How are they able to become superheroes in the culinary field? They are born with more visible taste papillae. These are those tiny dots everyone has on their tongue. Everyone has some visible versions of these dots, but these people have them in abundance.

This is useful but also problematic. Those with this tasting ability are more sensitive to foods, meaning that won’t be able to handle something that is very bitter, sweet, or salty. On top of this, they have more pain receptors on their tongue which makes them dislike spicy foods. Many who have superhuman taste buds do not like vegetables due to their bitter taste but they are not usually out of shape. This is due to the fact that they also do not like to consume a lot of sweet or fatty foods.

Tetrachromacy

• Percentage Of People Who Have It: Less Than 15%

Likely one of the most useful rare genetic traits anyone could have is tetrachromacy. It is possible that many of the world’s greatest artists had some form of it. This genetic trait affects how a person sees our broad color spectrum. Normal people are born with three cones in our eye to see the spectrum but some are born with a rare fourth cone. This might not seem like a lot, but that extra cone allows them to see and specifically find the difference in up to 100 million colors.

People with three cones, normies, can only see up to 1 million colors. That is a massive difference. This trait can be seen in men, but more often affects women. In fact, it is estimated up to 12% of the world’s female population are tetrachromats. It makes you wonder… if many women are born with this fourth cone, why do we not hear about it more? Apparently, a rogue X chromosome inactivation can shut off the visibility of this fourth cone in some women.

Heart On Opposite Side Of Chest

• Percentage Of People Who Have It: Less Than 1%

It would be irresponsible of us to not first mention some important anatomy information. The heart is NOT on the left side of our chest. Rather, it’s in the middle of our chest. However, it does partially go into the left side with the valves and other critical sections of the heart. Therefore, this is why people tend to believe it is completely located on the left. Just remember the bulk of the heart is mostly in the center. However, some are born with their heart leaning to the right side instead.

This is a genetic trait that is referred to as dextrocardia. Since it is mostly the valves and other portions of the heart leaning to the right, there are no real negative consequences from it. The main heart is still in the middle, of course. Therefore, do not assume someone is from another universe due to their heart being toward the right rather than the left. It is speculated that this has happened for thousands of years, and no one was ever better or worse off from it.

High Altitude Tolerance

• Percentage Of People Who Have It: Less Than 5%

If you are wanting to climb Mount Everest, you’re likely going to have a guide. This will almost always be a member of the Sherpas. They have lived around these Tibetan mountains for generations. They know the mountains well, especially Everest, which is why they guide so many. This is the most dangerous job in the world, but the pay is massive for the Tibetan and Nepalese people. Due to being here for generations, these people have developed a rare genetic trait. They can breathe normally at high altitudes, which normally makes even the most experienced non-native climbers sick.

The gene these native people possess goes back 40,000 years. People known as the Denisovans lived in these mountainous regions, and the generations that followed began to develop their incredible genetics. This supergene they have causes an increase in the oxygen-carrying hemoglobin, allowing the body to distribute oxygen more effectively. People with this gene can perform major manual labor tasks in high altitudes without experiencing oxygen deprivation. They can also breathe well in lower altitudes and still keep their incredible ability when they go back into higher altitudes.

Blue Eye Color

• Percentage Of People Who Have It: Around 8%

Blue eye color is not normal in the slightest and anyone who has this color has a mutation in their genetics. This might sound weird or scary, but it’s not that big of a deal. It began thousands of years ago when people began moving out of civilizations in the Middle East and into colder European sectors. Melanin began to change for these people as they no longer operated as often outdoors due to the far colder temperature. Eventually, the white caucasian skin color came from this.

Yet melanin did not stop with skin color, it also affected hair color and eventually the eyes. When it comes to blue eyes specifically, a genetic mutation in the HERC2 gene is to blame. This mutation causes reduced melanin production in the iris, which can offer a beautiful blue color. However, the lack of melanin also means those with blue eyes will be more sensitive to light. For example, they might need sunglasses in even small sunlight or have trouble driving at night due to lights on the road.

Golden Blood

• Percentage Of People Who Have It: Less Than 0.5% (Only 43 People Have Ever Reported To Have It)

We should state that we do not literally mean blood made of gold or gold-colored blood. Rather, this name typically comes from the rarity of this blood type. It is so rare that most hospitals have only a small supply of it or none at all. The “golden blood” is officially called the RH Null blood type. Basically, those with this blood type are missing all of their RH-blood antigens. Interestingly, anyone with another rare RH blood type can accept this blood type from donors.

As you can assume, since RH blood types are rare themselves, having RH Null blood around to give to ANY within the RH group is massively valuable. That is why those with this blood type are asked to donate as much blood as they can, as the medical community needs it in hospitals. However, due to the need hospitals have for it, RH Null blood is heavily needed for those who study blood too. If RH Null people did not exist, it could take literally months to years to find a specific RH donor.
