-
A distal limb malformation with manifestation of complete or partial webbing between the third and fourth fingers and/or the second and third toes. Other digits may be involved occasionally. The phenotype varies widely within and between families, sometimes only the hands are affected and sometimes only the feet. Webbing between fingers may be associated with bony fusion of the distal phalanges. Inherited as an autosomal dominant trait.
