Mutations of the GLI2 gene are associated with several phenotypes including Greig cephalopolysyndactyly syndrome, Pallister-Hall syndrome, preaxial polydactyly type IV, postaxial polydactyly types A1 and B.

The possession of six or more digits on the hands and feet ( polydactyly ) usually has a genetic or chromosomal cause, and is not a case of vestigial twinning.

The animal variations he studied included bees with legs instead of antennae; crayfish with extra oviducts; and in humans, polydactyly, extra ribs, and males with extra nipples.

In addition to the study of genetic causes of polydactyly limb patterning models are used to simulate the congenital disorder at the limb, being able to explain the development paths of polydactyly.

Polydactyly is most commonly found on the front paws only, it is rare for a cat to have polydactyl hind paws only, and polydactyly of all four paws is even less common.

Occipital encephalocele is present in 60 % to 80 % of all cases, and post-axial polydactyly is present in 55 % to 75 % of the total number of identified cases.
49.
The presence of polydactyly in SSTM 5025 may have been an adaptation to moving across underwater substrates in a similar manner to some early tetrapods of the Devonian such as " Acanthostega ".

Though still rare, phenomena such as polydactyly ( extra fingers and toes, a symptom of Ellis-van Creveld syndrome ) are more common in Amish communities than in the American population at large.
