[Bird headed dwarfism in Seckel syndrome. Nosologic difficulties].Arch Pediatr. 1996 Jan; 3(1):55-62.AP
Seckel syndrome is a clinical picture which associates four main features: intrauterine growth retardation, microcephaly often due to craniosynostosis, orofacial dysmorphology with bird headed appearance and variable mental retardation which is present after several months. Malformations of the central nervous system, limbs, and hair, may also be observed. On the basis of 78 cases reported in the literature, the authors discuss the validity of the morphological features of the syndrome. It is likely that the variability in the expressivity of each symptom explains its heterogeneity. According to the radiological abnormalities, three different forms of the syndrome have been described. Seckel syndrome is a genetic disorder with autosomal recessive inheritance. Its ethiopatogeny remains unclear. Hopefully linkage studies will allow to map the gene in order to determine the underlying abnormal protein.
