Every person has a unique set of fingerprints, right? Well, not exactly. Researchers have documented a rare condition called adermatoglyphia in some members of a Swiss family, in which the usual fingertip skin ridges and swirls responsible for fingerprints are missing.

The condition is caused by a mutation in a single gene that is expressed only in the skin.
