Three of the patients had been referred with a clinical diagnosis of Carpenter syndrome seewhich shows overlapping features with GCPS, including craniosynostosis and polysyndactyly; however, additional features that would point to Carpenter syndrome, such as fusion of the coronal or lambdoid sutures, high birth weight, umbilical hernia, and hypogenitalism in males, were absent in these patients.

If a cephalopolysyndactylyy of the proband has a balanced chromosome rearrangement, at-risk family members can be tested by chromosome analysis. One patient had full digit postaxial polydactyly of all 4 limbs, whereas the other had bilateral complete cutaneous syndactyly of the third and cepnalopolysyndactyly fingers, duplication of the great toe on the right with soft tissue syndactyly of toes 2 and 3, and medial deviation of the great toe on the left.
