Mutation linked with the absence of fingerprints

Scientists have identified a mutation that might underlie an extremely rare condition, called "adermatoglyphia," which causes people to be born without any fingerprints. The research, published by Cell Press online August 4th in The American Journal of Human Genetics, not only provides valuable insight into the genetic basis of adermatoglyphia and of typical fingerprint formation but also underscores the usefulness of rare genetic mutations as a tool for investigating unknown aspects of our biology.
