(1994) observed a distinct form of 'crossed' polysyndactyly in 6 generations of a family. The anomaly was transmitted from father to son through 3 generations, and a great-grandfather of the first of these 3 and a brother of one of the affected were said to be involved. Postaxial polydactyly of the hands and duplication of the great toe was the usual finding with cutaneous syndactyly between, for example, fingers 3 and 4 and toes 1, 2, and 3. The polysyndactyly is called 'crossed' because of postaxial involvement of the hands and preaxial involvement of the feet. Goldstein et al. (1994) took pains to point out that 'although this form of polysyndactyly had been described prior to 1978..., it and other complex forms of polysyndactyly were not classified by Temtamy and McKusick (1978).' The earlier reports included those of McClintic (1935) and Goodman (1965).
