Further delineation of the Simpson‐Golabi‐Behmel (SGB) syndrome

Abstract
The Simpson‐Golabi‐Behmel syndrome is an X‐linked condition characterized by pre‐ and postnatal overgrowth, “coarse” face, postaxial polydactyly, midline defects, and psycho‐motor development ranging from normal to mildly retarded. We report on an additional sporadic patient with novel manifestations, contributing to a more thorough delineation of this syndrome.
