Why people do not have fingerprints?

When a Swiss woman entered the United States, she claimed that she and 9 of her family had no fingerprints. They began to undergo genetic analysis to determine the cause of this phenomenon.

Finally, scientists have determined the cause behind this rare disease is the gene.

People with a rare disease called adermatoglyphia have no fingerprints .

Professor Eli Sprecher of the Department of Pharmacy at Tel Aviv University (Israel) and Tel Aviv Sourasky Pharmacy Center and colleagues have compared the genes of those who are ill and not sick to determine where genetic changes are located.

They discovered a version of the SMARCAD1 gene that specifically affects the development of fingerprints. The results of this study are published in the American Journal of Human Genetics . Now scientists continue to study how this gene affects fingerprint formation.

Just like DNA, each person's fingerprints are unique so it is a valuable tool for detecting crime in international travel. They are used for identification because they form fully after 24 weeks of conception and remain unchanged throughout life.

In 1930, the infamous gangster John Dilinger suffered to destroy his fingerprint with acid to escape the crime.

In 2009, a Chinese woman named Lin Rong entered Japan illegally by surgery to change fingerprints at a cost of about $ 15,000. Police are concerned that biometric fraud is quite common in China, with surgical brokers receiving a large amount of money.
