Adermatoglyphia

Adermatoglyphia is an extremely rare genetic disorder that prevents the development of fingerprints, so affected people are born without the ridged patterns normally found on the fingertips. Five extended families worldwide are known to be affected by the condition. Professor Peter Itin informally nicknamed it immigration delay disease after his first patient had trouble traveling to the United States because he had no fingerprints for identification. The condition is recorded here as a documented curiosity of human genetics and skin development, with the lead source describing its rarity and its practical everyday consequence rather than any wider medical picture.
