en تخصصي Special گزارش مورد case report Apert syndrome is a congenital craniosynostosis syndrome comprising of bilateral coronal synostosis , symmetric syndactyly of hands and feet and midface hypoplasia. We present an atypical phenotype of this syndrome with right sided unilateral coronal synostosis. However, type I apert hand and other clinical and radiological features suggestthe diagnosis. Genetic analysis revealed an absence of the specific missense mutations in the FGFR 2 gene that is found in patients with this syndrome. We conclude that this patient represented a rare atypical variant of Apert syndrome. Further analysis is required to map the associated genotype.
