RARE MUTATION--A CRIMINAL'S DREAM
Human skin has ridges called dermatoglyphs that are present on the fingers, palms, toes and soles. The dermatoglyphs on the finger tips, better known as fingerprints, are often used as a means for establishing identity. In fact, adermatoglyphia was recently named "immigration delay disease" because affected individuals report significant difficulties entering countries that require fingerprint recording. "We know that fingerprints are fully formed by 24 weeks after fertilization and do not undergo any modification throughout life," explains the senior study author, Dr. Eli Sprecher from Tel Aviv Sourasky Medical Center in Israel. "However, the factors underlying the formation and pattern of fingerprints during embryonic development are largely unknown."
