Polydactyly is an abnormality characterized by extra fingers or toes. The condition may be present as part of a collection of abnormalities, or it may exist by itself. When polydactyly exhibits by itself, it is inherited as an autosomal dominant trait.


Narration



Polydactyly is a malformation that includes extra fingers or toes. This condition is commonly inherited, and it may be part of a syndrome, that is, a number of other malformations that tend to appear together in the same individual. And it can be inherited, or it can be sporadic or non-genetic.
