Craniofacial pattern similarities and additional orofacial findings in siblings with the Robinow syndrome

This study elucidates a craniofacial profile pattern similarity among four family members with the Robinow syndrome. Using eight angular measurements, these profiles (created from standard scores and correlation coefficients (rz) among siblings) exceed 0.80. Dental examination of these same children demonstrates an unusual incisal edge morphology that could comprise one additional identifying feature in this disorder. The accumulation of findings in this study, along with those previously reported, emphasizes midline craniofacial involvement in the Robinow syndrome.
