Oligodactyly

A child with oligodactyly

Oligodactyly is a limb deformity that starts at birth where a person has less than five fingers or toes on a hand or foot.[1] It is usually caused by a heredital or genetic mutation.[2] It can also be a sign or symptom of a few syndromes, including Poland syndrome and Weyer Ulnar Ray Syndrome.[3]

Often, people with oligodactyly are able to do daily tasks without difficulty.[4][5] Even those with the worst forms of the condition can still do many things that need fine control, such as writing[4] and boot-making[5] as well as working as a taxi driver.[5]

Notably, many of the Vadoma people of Zimbabwe have oligodactyly.[6]
