The world of genetics is amazing! Although we are all born with our own unique but generic qualities, every now and then someone is born with a genetic mutation that stands out from the rest. Regardless, these traits are beautiful because they are unique.

Here are ten unique hand and foot genetic mutations that will make you look twice!

"Ulnar Dimelia" or Mirror-Hand Syndrome

The genetic condition is called “Ulnar Dimelia”, a perosn born with eight fingers on one hand that looks like they are holding hands, or even high-fiving themselves.

There are less than 100 cases of Ulnar Dimelia that have been recorded in medical literature worldwide.

Ectrodactyly aka “Lobster Claw Hand” or Foot

People with ectrodactyly, also known as a split-hand/split-foot malformation have a cleft where the middle finger or toe should be.
This causes their hand or feet to have a claw-like appearance.

This condition happens once in every 90,000 births.

Double Toe

Two examples of people born with double toes.

Missing Ring Finger And Pinky

Another example of the condition called ectrodactyly, which results in the middle of the hand developing in a way that is not as common, resulting in a finger.

Studies show that about 10% of babies in the world are born with a variant of this exact genetic condition.

Triphalangeal Thumb

Talk about The Longest Thumb Ever - a condition called “Triphalangeal Thumb.” All fingers are a normal length, with the exception that his thumb is basically as long as his index finger.

Only about 25,000 children in the world are born with this unique trait.

Extra Toe

This newborn baby was born with 12 fingers and 12 toes. A condition called polydactyly.

The feet and hands are proportionate, they just happen to have one extra digit on each hand and foot.

“Backwards Hand”

People who are double jointed don’t actually have two joints, however, their joints can move beyond their normal range.

Double-joints also called hypermobility have roughly only 5% of adults in the world have this genetic ability.

Long Toes

A girl with toes as long as her fingers. I think she may have broken the world record for longest toes

One of her fingers actually measures as long as 5 centimetetrs.

Webbed Fingers

“Syndactyly” is basically a fancy term for someone who has conjoined toes and fingers.

Atleast 1 in every 2000 kids in the world are born with this birth defect every year, so though the condition is rare, it’s more common than you think.

Split-Hand Formation

Another form of syndactyly of the thumb with the index finger in the upper limbs.

Ectrodactyly–ectodermal dysplasia–cleft syndrome is a rare orthopaedic malformation with incidence of around 1 in 90,000 births.
