Arachnodactyly ("spider fingers") or achromachia, is a condition in which the fingers are abnormally long and slender in comparison to the palm of the hand. It can be present at birth or develop in later life.[citation needed].

Causes[edit]

This feature can occur on its own, with no underlying health problems. However, it can also be associated with certain medical conditions. Examples include Marfan syndrome,[1] Ehlers-Danlos syndrome,[2] Loeys–Dietz syndrome and homocystinuria.

Arachnodactyly has been linked to mutations in both fibrillin-1 and fibrillin-2 genes.

Notable cases[edit]

It remains unconfirmed whether composer Sergei Rachmaninoff's abnormally large reach on a piano was a result of arachnodactyly due to Marfan syndrome, as the pianist exhibited no other signs of the disease.[3]
