Most people are born with 3 large wrinkles on their palms. But their thickness, thinness and clarity depend on the gene.

In rare cases, people have a prominent line instead of three. The rate of this case is 1/30 people. It is called "single wrinkle in the palm of the hand" and this case is very normal. But sometimes it indicates abnormal growth. Doctors can see it as a sign of: Down syndrome, fetal alcohol poisoning syndrome, turner syndrome, measles, aarskog syndrome.

However, there is no scientific evidence about hand reading.
