What does the Simian Line or Crease on Your Palm Mean?

What is a simian line?

Our baby recently had her nine month checkup and our pediatrician took a long look at her hands. Apparently, pediatricians check baby's palms for a Simian line or crease as a marker for a variety of genetic and chromosomal problems, however, there is a small percentage of the population that have a single line on their palms with no other issue. Our baby falls into that percentage and our pediatrician told me not to go home and Google "simian line," so of course when I got home the first thing I did was to ignore his advice. Here's what I discovered:

  • A simian line is where one line cuts across the palm.
  • A simian line or crease is a fusion of the head and heart line on the palm it is also referred to as a "single transverse palmar crease."
  • In palmistry this implies a person who cannot distinguish between thoughts and feelings, it means intensity and the ability to put heart and mind into anything.
  • It is possible to have a simian line on one hand and have the two split lines on the other.
  • Males are more likely to have a simian line or crease.
  • Asians and Native Americans are also more likely to have a simian line with no genetic or chromosomal issue.
