How many people have 11 fingers?
Radial polydactyly refers to the presence of an extra digit (or extra digits) on the radial side of the hand. It is most frequent in Indian populations and it is the second most common congenital hand disorder. The incidence of radial polydactyly is reported as 1 in every 3,000 live births.
How common is it to be born with 11 fingers?
It is a common condition that often runs in families. The extra fingers are usually small and abnormally developed. Polydactyly is one of the most common congenital (present at birth) hand abnormalities. About one out of every 500 to 1,000 babies are born with the condition, usually with only one hand affected.
Why is polydactyly rare?
Dominant But Rare
So if there are many dominant versions of genes that make six fingers, why is having six fingers rare? Well, those versions of genes are rare. You don't meet many people with extra fingers or toes. This means when two people meet and have a baby, odds are neither has the “six-finger” copy of a gene.

What causes extra digits at birth?
There are some underlying conditions, however, for which polydactyly is a symptom. These conditions include McKusick-Kaufman syndrome, Pallister-Hall syndrome, and Bardet-Biedl syndrome. If your child has other physical or developmental differences, you can talk to your doctor about the cause.

Which gene causes polydactyly?
GLI3 gene mutations can cause several forms of isolated polydactyly. These include postaxial polydactyly type A (PAP-A) and type A/B (PAP-A/B), which are characterized by an extra digit next to the little finger or the small toe.

Is polydactyly inherited?
Polydactyly may be passed down in families. This trait involves only one gene that can cause several variations. African Americans, more than other ethnic groups, can inherit a 6th finger. In most cases, this is not caused by a genetic disease.
What is the life expectancy of polydactyly?

The extra digit is well formed and articulates with the fifth, or extra, metacarpal/metatarsal, and thus it is usually functional.

Fingers have been demonstrated to differ in their motor ability in experiments that explored grip strength as well as when measuring produced forces for each finger individually: middle and index fingers were stronger than ring and little fingers, and the little finger was the weakest overall (Li, Latash, & Zatsiorsky, ...
Which finger is connected to the brain?
The thumb represents the brain, the index finger represents the liver/gall bladder. The middle finger represents heart, the ring finger represents hormones and the little finger or pinky represents digestion.

Does polydactyly skip generations?
As a result, it may appear to "skip" a generation. Since polydactyly is usually repaired early in life and may be forgotten or not discussed in families, ascertaining a complete family history of polydactyly may be difficult.
What chromosome does polydactyly affect?
A number sign (#) is used with this entry because of evidence that postaxial polydactyly type A1 (PAPA1) and type B (PAPB) are caused by heterozygous mutation in the GLI3 (165240) gene on chromosome 7p14. See also preaxial polydactyly type IV (174700), an allelic disorder.
