Some People Don’t Have Fingerprints, is That True?

Some People Don’t Have Fingerprints, is That True?

It is so. Fortunately, only a few percent of individuals suffer from this disease called adermatoglyphia – today it is described in only a few families in the world. This absence can make a problem especially when traveling or identifying a person if they commit a crime.

Fingerprints are unique proof of the identity of a person who can be identified from birth and throughout life. There are also exceptions that the grooves on the fingertips did not form. This phenomenon should develop in a healthy individual (embryo) at week 24. If this process does not happen, the mutation of the SMARCAD1 gene, which encodes one of the proteins in the skin and hinders the development of skin furrows, is to blame. Therefore, some people simply never develop fingerprints.

There have also been many attempts to trick dactyloscopy. People tried cutting off the fingertips, acid etching, or dipping their fingers in hot oil. In all cases, however, it has been shown that when the skin on the fingers is restored, the original pattern has been restored. The only exception was a few cases where criminals managed to destroy the embryonic layer of skin. The prints were never renewed.
