Polysyndactyly

Definition:

Polysyndactyly, also known as preaxial polydactyly type IV, is a rare autosomal dominant limb malformation, caused by mutations in the GLI3 gene. It is comprising duplicated halluces, with syndactyly of preaxial toes, broad or duplicated thumbs, and syndactyly of the third and fourth fingers. GLI3 is regarded as a mediator of sonic hedgehog signaling regulating development at multiple sites such as the limbs, the lungs, and the brain.
