Summitt Syndrome

Summitt (1969) described 2 brothers with craniosynostosis and syndactyly which was severe in one and mild in the other. Both were obese. Intelligence was normal. The skull was towered, as in Carpenter syndrome (201000). The parents were first cousins. Obesity was the presenting complaint, at age 6.5 years, in the sporadic case of Sells et al. (1979). Cohen et al. (1987) concluded that Summitt syndrome and Goodman syndrome (201020) are variants of Carpenter syndrome.
