15 People Who Have Incredibly Rare And Unique Genetics

Some people are born with rare genetics that can make them appear different than other people. Some of these conditions are harmless are don’t actually impact the lives of the people affected very much, however, other conditions can make life much more difficult for people, and make every day tasks a big challenge.

Below are some of the most interesting of these genetic conditions, which were curated by BoredPanda.


An Iris that is split in half with two colors

A rare genetic condition called “sectoral heterochromia” causes the iris of the eye to appear in two different colors. Most cases are hereditary and with a person from birth, but in very rare cases they can be caused by diseases or genetic mutations. Though multiple causes have been posited, the scientific consensus is that a lack of genetic diversity is the primary reason behind heterochromia. This is due to a mutation of the genes that determine melanin distribution at the 8-HTP pathway, which usually only become corrupted due to chromosomal homogeneity. This condition also occasionally appears in animals.


Growing multi-colored hair and eyes

Somewhat similar to the previous genetic condition, Waardenburg Syndrome causes different eye color to appear in each eye and also causes different color hair to appear on each side of the body and face. People with this condition are often deaf also. There are four different types of the condition which vary in degree and areas affected.


Six fingers on each hand

The man in the image above has a condition called Polydactyly, which involves people being born with extra fingers or thumbs.


Mirror Hands

Ulnar dimelia, also referred to simply as Mirror hand, is a very rare congenital disorder characterized by an absence of radial ray, duplication of the ulna, duplication of carpals, metacarpals, phalanges and symmetric polydactyly. In some cases, surgical amputation is performed to remove the duplicate carpals, metacarpals, and phalanges. Approximately 70 cases as of 2015 have been recorded in medical literature, According to Wikipedia.


Missing Fingers

Amniotic Band Syndrome is considered an accidental event, and it does not appear to be genetic or hereditary. A strong relationship between ABS and clubfoot (also called “talipes”) exists. A 31.5% of associated clubfoot deformity and ABS can be correlated with 20% occurring bilaterally. Other abnormalities found with ABS include: clubhands, cleft lip, and/or cleft palate, and hemangioma


Double jointed

Some people are able to move their limbs in directions that most people can’t, they are often called “double jointed.” Hypermobile joints are common and occur in about 10 to 25% of the population and are more common in children than adults.


Elft Ears

Due to different shaped cartilege, some babies often have pointed ears, similar to the mythical elves.


Missing fingers

Symbrachydactyly is a congenital abnormality in which bones will be missing from the fingers and some fingers or toes may be missing, or much smaller than normal. This condition occurs roughly every 1 in 30,000 births.


symmetrical hair swirls

The child in the image above has some type of strange pattern in his hair that has mystified doctors and researchers, who are currently studying to see if the pattern is related to some type of genetic condition.


A scar in the eye

A macular pucker is scar tissue that has formed on the eye’s macula, located in the center of the light-sensitive tissue called the retina. The macula provides the sharp, central vision we need for reading, driving, and seeing fine detail. A macular pucker can cause blurred and distorted central vision.


Tentacles on the tongue

Some people report tentacles on their growing along the area under their tongue, and while this is benign in some cases, in others it can be early warning signs of serious disease.


Unusually pruney fingers

Some people get pruney fingers more quickly than others in the water, and while there is no official scientific explanation for this, some experts suggest that this could be a genetic trait passed down by our hunter/gatherer ancestors who were always walking barefoot through wet areas.


Born with three fingers

The person in the photo above has a condition known as ectrodactyly, which is also sometimes called cleft hand or split hand. The incidence of cleft hand varies from 1 in 90,000 to 1 in 10,000 births depending on the used classification.


Born without a nose bridge

There are a number of conditions that can cause a child to be born without a bridge in their nose, including cleidocranial dysplasia, children with neurodevelopmental delay, achondroplasia, Conradi-Hünermann-Happle syndrome, Cornelia de Lange syndrome, osteogenesis imperfecta, and Klippel-Feil syndrome.


Freckles on one side of the face

There is no genetic condition that causes people to be born with freckles on just one side of their face, but experts suggest that this is a very specific type of birthmark, that just happens to resemble a cluster of freckles.
