Tony Blair with simian creases


A dermatoglyphic pattern of a single deep transpalmar crease formed by fusion of proximal and distal palmar creases, which is classically seen in trisomy 21, but also in trisomies 13 and 9, fetal trimethadione syndrome, so called, because of its verisimilitude to the same crease in monkeys.

The crease may be seen in (arguably) normal individuals, including Tony Blair, Hillary Clinton, Muhammad Ali, Robert De Niro and others

Synonyms Simian fold, simian line
