Fronto-ocular syndrome: newly recognized trigonocephaly syndrome.

We describe an apparently unique disorder, Fronto-Ocular syndrome, present in a mother and her two daughters, and comprising trigonocephaly due to coronal and metopic craniosynostosis, ocular hypotelorism, ocular proptosis and ptosis, epicanthal folds, hypoplastic supraorbital ridges, elevated nasal bridge, thin philtrum, high-arched palate and a narrow bifrontal region. Both daughters have glabellar capillary hemangiomas, a congenital heart defect and mild developmental disabilities. Review of the literature failed to disclose any syndrome with similar findings. It is likely that this disorder represents an autosomal dominant condition, that arose as a new mutation in the mother. Mutational analysis of fibroblast growth factor receptor (FGFR) 1 and FGFR2 failed to identify the molecular basis of the disorder.

Simultaneous occurrence of two supernumerary autosomal ring chromosomes r(1) and r(16) in twins.

Ring chromosomes are estimated to occur in 3/10000 newborns and the simultaneous occurrence of two autosomal rings must be a very rare event. Recently, the characterisation of these markers using fluorescence in situ hybridisation (FISH) has greatly enhanced cytogenetic-phenotypic correlations in patients with these marker chromosomes. This kind of analysis enabled us to clarify a unique karyotype containing a r(1) and a r(16) in identical twins born after a 26 week gestation with minimal somatic abnormalities. The origin of the rings was identified using a satellite and whole chromosome painting probes. FISH analysis showed the same abnormal female karyotype in both twins, 48,XX,+r(1)(p13q21),+r(16)(p11q11).ish r(1) (D1Z5+,wcpl+), r(16)(D16Z2+,wcp16+) in about two thirds of the cells. Each also had minor clones with a normal female karyotype or with one or the other supernumerary ring. Half of the r(1) contained CBG band negative material and the r(16) appeared to be totally CBG band positive. These twins represent the second report of the simultaneous occurrence of multiple autosomal rings. Their description may help to delineate a new chromosome disorder and shows the usefulness of FISH analysis.

Central nervous system anomalies in Seckel syndrome: report of a new family and review of the literature.

Seckel syndrome (SS) is a rare, heterogeneous form of primordial dwarfism. The clinical delineation of this disorder has been inconsistent, using even Seckel's original criteria. As a result, probably fewer than one-third of reported cases are truly affected with SS. Among these, there have been only six familial cases, all of whom were born to normal parents, and in only one case has a detailed description of the central nervous system (CNS) anomalies been given. We describe a family in which three of eight children were affected with SS. CNS anomalies seen in our patients included agenesis of the corpus callosum, a dysgenetic cerebral cortex, a large dorsal cerebral cyst, and pachygyria, suggesting an underlying neuronal migration disorder. The parents are first cousins, representing only the second instance of consanguinity, supporting an autosomal recessive mode of inheritance.

The Marshall syndrome: report of a new family and review of the literature.

The Marshall syndrome is an autosomal dominant trait comprising ocular abnormalities, sensorineural hearing loss, craniofacial anomalies, and anhidrotic ectodermal dysplasia. To our knowledge, only seven additional multigenerational families have been reported since the initial description of the disorder by Marshall in 1958. We present a family in which six members in four generations are affected with apparent Marshall syndrome. We also review and compare similar disorders, such as Stickler, Weissenbacher-Zweimüller, and Wagner syndromes, and conclude that Marshall syndrome is a distinct entity.
