Greig cephalopolysyndactyly syndrome
P. A. Duncan, R. M. Klein, P. L. Wilmot and L. R. Shapiro
Based on the family presented and five others previously described, it can
be concluded that the Grieg cephalopolysyndactyly syndrome is a fully
penetrant autosomal dominant disease consisting of four variably expressed
malformations: postaxial polydactyly (type B), preaxial polydactyly,
syndactyly, and minor craniofacial abnormalities. This entity can be
differentiated from other craniofacial-digital syndromes because of the
absence of mental retardation, craniosynostosis, and brachydactyly.
