The Single Palmer Crease

Have you ever looked at the palm of your hand?  Did you ever give any thought to it?

Most people have three strong lines (called palmar flexion creases) in the palms of their hands.  Palmar creases develop while a baby is in the womb (usually by week 12 gestation).

A Single Palmar Crease is a single line that runs across the palm of the hand; the horizontal creases join together to form a single one. 

This used to be called a 'Simian Crease' but that carried a negative connotation (as it refers to a monkey or ape).

Some Interesting Facts:

  • The Single Palmar Crease occurs in 1 out of 30 individuals. 

  • Males are twice as likely as females to have it. 

  • Single palmar creases usually indicates a problem with development.

  • The Single Palmar Crease is more prevalent in individuals with: hyperactivity (2-3x more), neuroticism, delinquent behavior, and schizophrenia.

  • About 45% of people with Down Syndrome have the Single Palmar Crease; Compare that to 1% of the general population.

Josiah is one of the 55% of children with Down Syndrome who does NOT have the Single Palmar Crease.

Famous People that have the Single Palmar Crease (or close variation):

Albert Einstein
Muhammad Ali
Tony Blair
Hillary Clinton
Robert DeNiro
